    Why Get an AR-15 Upper Receiver Assembly?

    Quick refresher on AR-15 uppers and lowers…

    Chances are you already have a complete AR-15 rifle or at least the serialized complete lower. 

    By pushing out two pins to disconnect the upper from the lower you can:

    • Save Money: If you’re not looking to get two guns and just want a different AR, getting the upper by itself will save you at least $150+
    • Save Time & Paperwork: Since only the lower is serialized, you don’t need to go to an FFL and file paperwork.
    • Keep Your Loadout: You’ve already modified your trigger, buttstock, or grip to your liking and don’t want to do it again.
    AR-15 Complete Lowers
    AR-15 Complete Lowers

    We’ll be going over completed AR-15 upper assemblies or groups that have the barrel, handguard, BCG, and more, instead of just the stripped upper.

    But don’t worry; here’s our guide for the Best Stripped Uppers for your build and how to put it all together: Upper Guide & Lower Guide.

    How We Tested the Best Complete AR-15 Uppers

    We test, build, and shoot A LOT of AR-15s in our time at Pew Pew Tactical.

    Lots of AR-15 Uppers
    Lots of AR-15 uppers…yup, we love them

    We made sure that all general-use uppers chosen had at least 1000 rounds through with different types of ammo and over at least 6-months of shooting.

    Our accuracy score dictated the upper must be capable of shooting at least 2.5″ MOA at 100 yards with at least one type of ammo.

    LWRC IC-SPR Groups
    100 Yard AR-15 Groups

    While our reliability score gave a 100 round break-in period where we allowed some failures to feed and extract. Any reliability issues after 100 rounds eliminated the upper.

    We then also judged the uppers in terms of more subjective areas such as value, ergonomics, and looks.

    And because there’s so many roles that an AR-15 can fulfill we broke down our choices into categories:

    • Best 16″ Complete AR-15 Uppers
    • Best Short Barrel AR-15 Uppers
    • Best Pinned AR-15 Uppers
    • Best Other AR-15 Uppers (Lightweight, Left-Handed)

    Best 16-inch AR-15 Uppers

    These are the most popular upper receivers since they are in the sweet spot of 16″ barrels…the minimum barrel length for a rifle under the National Firearms Act (NFA).

    We prefer mid-length gas systems for 16-inch barrels since they allow a little more space for pressures to drop and therefore give a slightly softer shooting impulse.

    Other things such as handguards, front sight block (FSB), and barrel profiles are user preferences.

    Pros

    • Top-tier brand and upper
    • 100% reliability
    • Best for under 00
    • Lots of customization options

    Cons

    • Sometimes specific models out of stock

    Bravo Company Manufacturing (BCM) is another top-tier brand that’s very highly regarded.

    And if we had to choose one upper for most people it would be their 16″ mid-length with MCMR handguard that comes in under $1000 even with all the upgrades.

    We’ve been testing ours since 2020 with thousands of rounds by now and it has been nothing but flawless.

    BCM Recce-16, Running
    BCM 16, Running

    Its bolt carrier group (BCG), or the “engine” of the upper, is the gold-standard of BCGs.

    BCM 16" Mid-Length MCMR Handguard
    BCM 16″ Mid-Length with 15″ MCMR Handguard

    And while you can get other lengths of handguard, we especially like the full-length 15-inch MCMR handrail in M-LOK to give you tons of space to mount anything your heart desires.

    BCM Front and 15" MCMR Rail
    BCM Front and 15″ MCMR Rail

    Accuracy is decent with 2-3 MOA across the spectrum of ammo types. Keep in mind 4 MOA is the standard for the US Military. And this rifle is more of a reliable workhouse kind of AR.

    • Wolf Gold 55gr: 3 MOA
    • PMC 55gr/American Eagle 55gr/XM193 55gr: 2-3 MOA
    • Federal Gold Medal 69gr: 2 MOA
    BCM 16" Groups
    BCM 16″ Groups

    See it in action here:

    There’s also a couple different variations, but we recommend the following specific build:

    • BFH: barrel forged hammer for longevity and accuracy
    • 15″ MCMR handguard: aesthetics and more mounting area
    • Standard barrel profile: not the Enhanced Light Weight so it’s more balanced and has better cooling
    • MK2: gives the upper receiver more rigidity and vents away gas
    BCM MK2 Upper Difference
    BCM MK2 Upper Difference

    Once inside you can also choose a couple things:

    • BCM BCG: it’s the gold-standard and it should come with it for free
    • Charging handle: they are ambi and really nice, I like the medium for most
    • Muzzle device: the free A2 flash hider is great to start with

    • BCG is top-notch
    • Very well tested brand and model
    • Ultra reliable
    • 1 MOA shooting group with heavier rounds

    Cons

    From our go-to high-end complete AR is the Daniel Defense DDM4 V7 upper that brings everything top-notch.

    See it in action:

    We’ve been shooting this upper for years and the round count is in the thousands. And it has been 100% reliable for us even when suppressed.

    Accuracy is standard for 55gr plinking rounds at around 2-3 MOA (which is still plenty enough for most uses). But if you put in heavier match ammo like 69gr Federal Gold Medal you can get it down to 1 MOA.

    Daniel Defense DDM4 V7 66-grain ammo target

    Pros

    • Soft shooting 16" mid-length gas system
    • 100% reliable with our tests
    • Different colors u0026 rails available

    Cons

    • Need to add BCG & charging handle

    Aero Precision has long been regarded as the best value in the world of AR-15s. And it’s around $700 for a complete upper that looks great and runs 100%.

    It has a softer shooting mid-length gas system, 16-inch CMV barrel, choice of free-floating rail, but you will need to add a BCG and charging handle for about ~$200 more than what you initially see (use the “Finish Your Build” tab).

    Aero Precision M4E1 16 Midlength Pencil
    Aero Precision M4E1 16 Midlength Pencil

    It’s been through a lot of rounds and testing…and now sits as one of my home-defense rifles.

    Accuracy was surprisingly great with a 1 MOA group with affordable PMC 55gr ammo. While XM193 yielded a more normal 2-3 MOA.

    Pros

    • Lots of options
    • Affordable and always goes bang

    Cons

    • Finishes could be better

    PSA is the AR-15 behemoth that has a very nice vertically integrated manufacturing process. AKA…they make everything themselves in the US to save you money.

    There’s tons of options from PSA, but here’s our fav with a 16-inch mid-length barrel sporting an M-LOK free-floating handguard.

    PSA 16" Nitride Free Floating
    PSA 16″ Nitride Free Floating

    You can still choose BCG, sights, and barrel profile.

    Or if you already have a BCG and charging handle…you’ll save even more by getting a rifle kit or one without BCG/CH.

    You’ll hear the occasional complaint about finish and shipping time…but they are well-known online for reliability

    At the end of the day, that counts the most.

    PSA 5.56 & .223 Wylde
    PSA 5.56 & .223 Wylde Uppers

    Accuracy is great for the price point with 2-3 MOA groups with most 55gr such as Wolf, PMC, & American Eagle. One thing to note is that with Gold Match 69gr ammo the group stays 2 MOA.

    PSA Free Floating Accuracy

    Our PSA uppers have been tested with everything from multiple optics to suppressed and even full-auto. So far…100% reliability.

    Best AR-15 Short Barrel Uppers

    These sub 16″ barreled uppers are for Short Barrel Rifle (SBR) applications or the easier-to-do AR-15 pistol configuration. 

    Expected range of use is most likely under 100 yards but can go out to 2-300 yards.

    Aero AR-15 10.5" Pistol
    Aero AR-15 10.5″ Pistol

    Make sure you follow all laws, such as having a pistol lower already before purchasing.

    I like the minimum length for 5.56 to be at least 10 inches because of increased dwell time, velocity, and reduced gas/noise.

    Pros

    • Cool nostalgia factor
    • Proven reliability

    Cons

    • Gassy especially when suppressed

    The MK18 is the current rifle being provided to US Special Operations Command.

    This upper comes with a 10.3-inch government profile, 1:7 twist, carbine length gas system, and flash suppressor.

    And the Daniel Defense MK18 upper is the current go-to civilian variant.

    Daniel Defense MK18
    Daniel Defense MK18

    We’ve put tons of rounds through our MK18 uppers with the majority of it suppressed. And even some full-auto.

    It’s eaten thousands of different rounds and never stopped chugging.

    Daniel Defense MK18
    Daniel Defense MK18 Full Auto

    The only complaint we can give is that it’s a little gassy when suppressed. However newer flow-through cans help immensely.

    The DD MK18 is also well-known for its accuracy with accounts coming in at 1 MOA with good ammo.

    We haven’t put it on paper despite all the rounds we’ve shot. But it’s been accurate on small steel at 200 yards and touching bullet holes at 25.

    DD MK18 SBR
    Another DD MK18 SBR

    Check out our full review of the DD MK18. And note that you can purchase the upper with or without the charging handle and BCG.

    Pros

    • Less blowback and less recoil
    • Ready to accept Dead Air suppressors
    • Great lengths of 11.5" and 12.5"

    Cons

    • Hard to keep in stock

    Another great choice if you want to up the length a tiny bit but gain some smoother shooting and even less gas in your face. Plus save 10% with code PEWPEW10.

    Rosco K9 12.5" Upper
    Rosco K9 12.5″ Upper

    Rosco’s K9 12.5″ barrel uses a proprietary “Patrol Length” gas system that’s definitely softer shooting than carbine and more reliable than mid-length.

    Plus its continuous taper allows for even heat distribution and a more balanced rifle towards the middle.

    Rosco 11.5" vs 12.5" K9

    The complete uppers also come with SOLGW Nox flash hiders which attach popular Dead Air suppressors.

    Rosco Upper, Closeup
    Rosco Upper, Closeup

    Made in conjunction with the awesome guys over at Sage Dynamics…I’ve had a great time shooting the 12.5″ K9, which so far has been 100% reliable and dead-nuts accurate on paper and easy hitting at 200 yard steel.

    Newer Rosco upper receiver groups are now upgraded with a “wedge lock” system that really secures the handguard to the upper receiver…like this 11.5″ build.

    Rosco 11.5" Build
    Rosco 11.5″ Build

    You can see the difference at the bottom of the handguard closest to the upper receiver. Instead of two screws there’s now one underneath.

    Cons

    • Finish could be better sometimes

    Not wanting to have much barrel length AND out-of-pocket expense?

    Again…it’s PSA to the rescue. Normally short ARs have reliability issues but so far, so good with PSA. 

    PSA AR-15 Pistol Uppers
    PSA AR-15 Pistol Uppers

    See the 10.5 inch in action:

    PSA 10.5" AR-15 Upper Groups
    PSA 10.5″ AR-15 Upper Groups

    The 7.5″ was not so great in the accuracy department. Plus it gave an excessive amount of noise and pushback. I’d recommend going with at least the 10.5″ for most AR pistol uses.

    We conducted a full review with their 10.5-inch and 7.5-inch (for those who want to go ultra-short).

    Aero 10.5" Upper
    Aero 10.5″ Upper

    But you need to purchase a BCG and charging handle (~$200 in the “Finish Your Build” tab). However even with that addition you get the best value in the price range.

    Aero AR-15 10.5″ Pistol

    Ours has been fun to shoot and we’ve gotten just over 1000 rounds through it. It’s been 100% reliable and made it to truck gun status.

    Best Pinned AR-15 Uppers

    Want your AR to be as short as legally possible without dealing with a pistol brace or SBR?

    Enter the 14.5″ barrels with a pinned muzzle device which saves you about 2-3″ from adding a muzzle device to a 16″ barrel.

    • Sometimes out of stock

    Yes, we love BCM as do tons of other people.

    I haven’t had a more balanced feeling and lightweight rifle than this one.

    Complete BCM AR-15s (L to R), 11.5″, 16″, 14.5″

    Reliability has been top notch through 1000 rounds and we have a couple classes coming up where we’ll be using it as our primary.

    Accuracy is decent too when we bench tested.

    And the results:

    • AAC 55gr/AAC 77gr/PMC Bronze: 2-3 MOA
    • Gold Medal 77gr: 2 MOA
    • Gold Dot 55gr: 4 MOA

    Keep in mind again BCM goes for ultra-reliable workhouse rifles instead of tack-drivers. The 2-3 MOA is enough for all my intended purposes.

    BCM 14.5 Upper Build
    BCM 14.5 Upper Build

    And because the muzzle device is pinned you’re not going to put on a suppressor…and with the lightweight barrel it would totally throw off the balance anyways.

    Again, there’s tons of choices and we highly recommend their 14.5″ pinned upper especially in the MK2 receiver and Enhanced Light Weight barrel configuration.

    Of course get the BCG and I like the Ambi Medium charging handle.

    BCM Medium Ambi Latch

    For Muzzle Device it’s your choice but I like the flash hider or if you want some recoil reduction…get one of the comps.

    No added frills but the handguard is decent and M-LOK compatible.

    Plus the BCG and charging handle are mil-spec and correctly staked.

    After some break-in I set it up for accuracy testing with a Triggertech 2-stage trigger and S&B 5-25x scope.

    Slow but steady shooting with some different rounds.

    Here’s the results:

    • S&B 5.56 M193 55gr: ~3 MOA
    • Speer Gold Dot .223 55gr: ~2.5 MOA

    It seemed a little more agnostic to ammo and I’m glad the defensive ammo came in the best shooting. Regardless…still better than most mil-spec guns.

    Plus it has been 100% reliable for around 500 rounds…but we’ll keep shooting!

    Want some other calibers? They’ve got other options such as .300 BLK and 7.62×39.

    I like this model for the rails, although there are other options if you want a front-sight block.

    Since none of us on the PPT team are lefties we only shot this for around 100 rounds before switching back to the correct way :-).

    Background and Brands

    Technical Background

    We’re going to presuppose that you already know some stuff about AR-15s, such as the different barrel lengths, gas systems, and BCGs. 

    If you’d like a refresher, check out our Guide to AR-15s.

    We’re also sticking with direct impingement guns (normal). If you’re looking for piston uppers…check out Best Piston Uppers & Kits.

    Direct Impingement
    Direct Impingement

    Brands

    These are our perceived top-tier brands that don’t skimp but cost a little bit more. If you’re looking to trust your rifle with your life, we recommend these proven brands.

    • Bravo Company (BCM)
    • Colt
    • Daniel Defense (DD)
    • Larue
    • Lewis Machine & Tool (LMT)
    • LWRC
    • Noveske

    And these are our mid-tier brands. There’s nothing wrong with them, and we own a couple ourselves for plinking and competitions. But we recommend testing them thoroughly before you decide to use them for defensive purposes. These will typically cost less than the top-tier brands.

    • Anderson
    • Aero Precision
    • FNH
    • Palmetto State Armory (PSA)
    • Rainier Arms
    • Ruger
    • Sig Sauer
    • Smith & Wesson
    • Spike’s

    Finally, these are the budget-tier brands. Cheapest of the bunch but great for a starter build. Probably missing some accessories, such as a free-floating barrel.

    • Bushmaster
    • Delton
    • DPMS
    • Olympic
    • Rock River Arms (RRA)
    • Stag

      I would have thought Spikes Tactical would have been on the top tier list ? As they say the finest ARs on the planit .

      Was reading along happily until I got to the first upper. $800? For an upper? That's twice what my AR cost! And my Bear Creek upper in 7.62x39 was under $200 - complete. And $1,200 for the next one? These are not "deals" - these are what Veblen called "conspicuous consumption."

      My uppers put bullets in the same holes as these for a fraction of the price. For the price of just the second upper, I've bought: an AR, an M-LOK handguard, a folding stock, a 7.62x39 upper, a CMMG .22 lr insert with 3 magazines, a spare lower, an inexpensive but perfectly usable lighted variable PIC rail scope with laser, flip-up open sights, and an ATI .410 gauge upper. By any stretch, these prices are, er, less-for-more nuts.

      ARs, I think, should not be measured on the same scale as a conventional rifle - i.e. driving tacks. OK - if you're competing in an AR-only accuracy match, so be it; but for their intended niche, reliable cycling with low recoil is almost the whole deal. You don't really need MOA accuracy unless it's your only gear - that's what bolt-action rifles are for.

      Just a thought; interesting article, but if whole ARs can be made and sold for $350 that work just fine, that fact should be highlighted in an article like this, I'd think.

      On the BCM, PewPew says they recommend the "Standard barrel profile: not the Enhanced Light Weight so it's more balanced and has better cooling” This is absurd. The standard Gov profile sucks and everyone knows it’s inferior to modern barrel profiles.
      Definitely DO GET THE ELW OR EMW PROFILE. They have a modern taper and will be better at handling and more balanced. It’s asinine that Pew says a gov profile is more balanced when a Gov profile barrel gets fatter and heavier at the muzzle end, making it front heavy and not as easy to balance and maneuver as an ELW or EMW profile. Even BCM themselves says that their enhanced profile barrels have "Continuous taper designed for optimal weight, balance, and performance. Tapered profile out front, for easier maneuverability." It is flat out wrong and a disservice to their users for Pew Pew to say the exact opposite and instead recommend an inferior standard government profile. It's why modern taper profile barrels like the Criterion CORE, BA Hanson, Faxon Gunner, and BCM ELW and EMW profiles exist. Everyone in the industry knows that these are better than a standard gov profile. Either the author made a huge mistake and flip flopped here, or he's just that uneducated. By the way it reads, it seems he's just that uneducated and confused by it, and doing a disservice for his readers.

      I would respectfully suggest you consider Sionics among the top tier builders. Literally dozens of local/state contracts they have fulfilled over the years speaks volumes even though their marketing doesn't say much at all. Their BCG's truly are the best in the business (NP3 coated w/OCKS gas keys - see the SOTR BCG review) and the uppers can be had for roughly the same price as a mid-tier. After thousands and thousands of rounds thru 16" & 11.5" suppressed uppers (perfectly gassed with no need for an adjustable gas block) with ZERO upper-related issues, they are my go-to for home defense, 2gun matches out to 500+, or high round count classes. There are lots of other makers that produce fun range toys or high priced marque brands, but Sionics is consistently reliable and accurate. They fly under the radar, and I'm glad because they remain affordable.

        I'm sitting here wondering WHY, pew pew rarely - if at all - mentions or rates the Super Duty. It is definitely the UPPER TIER and in my opinion surpasses the "all-mill-speck" Daniel Defense by leaps and bounds, and then I saw your post and realized
        I am not the lone ranger (thank you) Geissele is an innovator and they MAKE MOST OF THEIR OWN PARTS, where DD mostly uses mill speck made by others that they do quality control on. I'm not saying they are not good ..... just way over-hyped to me

      Great read as always from PPT however I would have to disagree with the tier list, (new) Stag arms can easily replace Anderson and PSA on the mid tier list and Sig Sauer and FNH could be bumped up to premium on account of CHM barrels and picking up recent mil contracts where old man Colt left off.

      Not sure why everyone thinks Colt products
      Are so great. They lost military contracts for a reason. I was involved in DoD testing of Colt against 2 other competitors (that is all there was at the time). Colt came in last in
      Every category we tested. Even today, they log more complaints about their uppers over
      Everyone else. The QC is lacking.

        Prices are not automatically updated and our staff isn't big enough to update thousands of prices in real-time across the site. A global health event combined with a US election year and civil unrest caused massive stockpiling, shortages in production, and panic buying that resulted in prices rising across the industry as supply plummeted and demand skyrocketed.

      I've built a few ar15s and an ar10 and have bought a few of them fully assembled. The Diamondback,2- DPMS, and Spikes Tactical were fully assembled The ar10 I built with a polymer lower with a Delta Team Tactical upper and an ar15 polymer lower with Ar15Tac.com upper. Each has different trigger assemblies and optics, Not to take away from your experience with ar15s but I'm not a list person and I buy what I like and can afford. Just because someone spends a bunch of money on a "top tier" rifle doesn't mean their not gonna have problems or accuracy issues. A lot depends on the person that owns the rifle, how they take care of it, the optics, the trigger, etc. My friend bought an aero precision cause he seen a list somewhere that they were better than one of the DPMSs I own. He found out that lists of high dollar rifles aren't all that when my DPMS out shot his. Out of all my ARs my first DPMS is by far my go to gun for hunting, range shooting, etc. I've shot more deer, varmints, hogs, with that rifle and have never had an issue of any kind and no, you didn't hurt my feelings by putting DPMS at the bottom tier my point is that people shouldn't be afraid to purchase any of the bottom tier rifles cause a list says you have to spend crazy money to have a dependable and accurate rifle. Its just not true.

        Oh my, you could build a pair of beautiful AR's with 2 grand. I've owned many, a couple of Delton 16"s, a Olympic Arms in x39, a few other piece meal ones, Bear Creek Arsenal, PSA (kit where I built the lower, SUPER simple and easy BTW) 10.5" pistol by far my favorite go to since putting it together AND can carry it on my passenger seat loaded since I live in a Constitutional Carry state, and I had a couple of other AR's through the years too..
        I'd say for building something, Delton and PSA would be my first 2 choices. Anyway, just pick barrel length, what it's for, and go for it!

        September 22, 2020 2:02 pm
    • The Barber

      I know your pushing the larger length 14” uppers, but you may consider highlighting the smaller uppers I.E. BCM 11.5, Daniel Defense, and others- If you put a suppressor on a 11.5” upper the barrel size increases to 14-16”. A suppressed m4 is ideal for home defense since Your not blowing out your neighbors eardrums —ohh and the Katt with the super beard on Your Staff you may consider a charity Shave off and the proceeds go to shaving his beard. Besides that beard can get stuck in machine tools, burned up by hot objects or firearms of open bolt designs -can be a liability-even for ‘Pew Pew’.

        Hurting your neighbors’ eardrums should be your last concern in a defensive gun use. Even the concept of wearing ear protections yourself is debatable and imo a bit unrealistic in a stuff is hitting the fan situation.

      There is a lot of other factors involved in reliability and accuracy besides the design of a rifle. You don't have to spend crazy money to have a reliable and accurate AR either. I guess some people have to justify what They paid to buy or build their AR. BTW my 2 DPMS rifles have put some of those high dollar ones to shame at the range and in the field. If I miss that quarter at 200 yards I have 29 more rounds and my rifles not jamming.

      Can believe I just read all this... and then the comments. Anyone who says anything about “Price doesn’t equal quality” is a complete dolt. It means they don’t understand the firearm, the different manufacturers or their designs or end goals (reliability/ accuracy). Any $500 AR can throw a bullet a hundred yards, but few can cover a quarter at 200+. Those who understands this, understands the build process, the ammunition and the reason for the higher cost.... It’s not just laser etching on a pot metal.

        Mike I don’t disagree, but most shooters won’t notice the difference at the range in terms of accuracy. You have to be a great shooter or you have to put optic and go for targets at a longer range. Most lower end manufacturers are also good to go nowadays, you’re not going to have the fit and finish, and nice features such as the more durable barrel, better treatment on the BCG etc but for most situations and most people it will do it’s job

      The listed retailers are the end result of parts tree of life. The higher the price, the more middle men. Not necessarily, the higher the quality. You want to look for a combination of high quality individual parts, absolutely NOT mil-spec, the lowest quality, and performance tier; Combined with assemblers exhibiting high quality assurance (you're way past the quality control stage), and extreme attention to detail. So if you buy a rifle with a flag engraved on both sides, They should conform to either, official flag flying specs, like on a jeep, or aircraft; Or to your specific order specs. If you bring up quality control, or attention to detail, and the seller says- that costs money! Go someplace else, because the first three steps in making anything are, attention to detail, quality control, and quality assurance, before you charge penny one. I don't want to list my favorites after going through M's, AR's, and M's again since 1970! Luckily, with all officially supplied ammo. I want you, the future buyer, to become a well educated, well informed, conscious, buyer, so you can pay it forward.
      To review- price does not necessarily equate to quality. Mil-spec is the lowest quality level on the market. Endeavour to always exceed mil-spec. The critical components are- matched upper/lower sets that DO NOT open like a mil-spec hinge. Bolt carrier to upper receiver slop on fore/aft movement. Bolt to barrel extension precise, smooth, interaction. Bolt to bolt carrier precise, smooth, non wobbling interaction. Bore, centered precisely in the barrel. (BTSeenT). Barrel precisely, and correctly positioned in the barrel extension. Barrel extension, with correct feed ramp, correctly centered in upper receiver, to correctly feed a round. Correct chamber for your chosen round. I have had all 3. For me, the best, constantly reliable, was the 5.56 military chamber. It ate/eats anything. .223 chambers can be quirky with 5.56 rounds.. (ever found blown primers in your barrel extension? ) And the Wilde chambers can be quirky with all but specific sized reloads. So talk with the chamber expert in the shop when deciding which chamber to use/request. And recognize that AR-X may love one brand of ammo, and shoot it dead on where you want, but with super high priced g-whiz ammo, it may turn into a clunker gun!

      February 9, 2019 4:39 pm
    • el pedo viejo tirador

      There are only three or four actual manufacturers of many of the upper parts listed. Maybe 5! Using original M-16E2 source retail, plus - Government prices as a start, we can determine the ever increasing retail price andan indicator of the number of extra middle men involved. Lets start with a "mil-spec" rifle. Bottom of the barrel, lowest quality, minimal accuracy, must go bang, most of the time, sloppiest tolerances, no problem with parts wear out or breakage with constant depot, or armory level care and maintenance. - Milspec- had one issued for 35 years!
      Above mil-spec- difference is, attention to detail, quality control, and assembly tolerance quality. If you have an assembler that gets paid $2. per rifle to assemble it. The faster he can make it go click bang, the more he makes! If the gun comes back to be correctly rebuilt to correct original factory, shoulda been spec, it comes out of the assemblers time. They don't like that, and at some companies, the assembler, whose d code is stamped into the bottom of the grip frame, will do anything to avoid the issue. Especially with stainless steel, issue,law enforcement revolvers from a hour North of Hartford. Just something to be aware of.
      But, if you get a rifle, built by a guy who is a professional, and who cares, and you get a box stock, matched upper/lower, rifle that shoots better than 1 moa, has had one malfunction that can't be explained in the first 3500 rounds, was overnight factory shipped corrected, then went 60,000 rounds without failure, and still shot 2.5 moa, with all stock, non mil-spec (above, due to attention to detail, and quality control), parts. For an, at the time, $800 rifle. That pretty much sets the standard of expectance. Colona, Il. must have special air!
      So a key component to getting a super- shoots where you think, never breaks gun, is to find the actual source of the critical component parts, like the barrel, or the matched, no slack, upper/lower assembly, and ask them, who uses their components.
      Like ask Brownells who makes their super excellent component parts, and start there. Many "assemblers" produce multiple tier quality levels. From the bottom end mil-spec stuff, to the exceptional quality, "ultra match grade, non mil-spec stuff" but make sure your chosen manufacturer can back up his grade level claims with product, not words or labels.
      If you have ever sat in front of the old Colt Hammer Forging barrel machine for an hourof havng your bones rattled, it gives perspective. If you've talked to Boots, and listened to his swiss time piece barrel machine in the background, it gves you perspective. If you go to Colona, Il. and get treated like family, it gves perspective. Or if you walk into a small production company, stacked to the ceiling with boxes of parts being supplied to 25 different AR rifle assembling companies, it gives perspective.
      Point is- research is fun, and a great learning experience. Investigate, go to the shot show and talk to everyone, big and small, especially small. Read the name tags of passers by. The heavy hitters at the show will be quiet guys walking the aisles, with no tables. Find they, talk to them, learn!

      A stainless steel barrel is not more inheriently accurate than a comparable chromoly barrel. The difference is in the gauging of the barrel after it is rifled. I also must take exception to your notion that Ruger or Smith and Wesson are less "top tier" than Colt or the other manufacturers you list as top. I have been a gunsmith for more than 35 years and have worked on all of these, not depend on them? Nonsense. You seem to be more impressed by the price than actual performance. I would put one of mine against anything you list as top tier.

      Some great information but really nothing at all to support the placement in a specific category. It may just be us mechanical engineers that want real data in the form of exactly what materials, coatings, design features, tolerances and dimensions, surface finish, heat treatments, it is that makes one widget better than another. Millions of bytes on the web and still not what we need.

        yes. the upper no, the suppressor yes. together, assembled, yes. it keys on the suppressor. of, if it's a ruger with the serial number on the barrel, yes, with a can attached.

      • Ron Alvarez

        Does POF make their own uppers? or have them made under contract for them? I really like the POF lowers, for attention to detail, and quality control, but only with a matched, non mil-spec, won't open like a clam, upper. For strength, check the torque specs they tested to the failure point in screwing on the barrel nut. While put it together spec is one thing. Failure spec tells you the quality of the upper, metal. When you attach the upper to the lower, it should sound like an mp-5sda3 with a wet supressor. shick-aaah! It should no go clunk clunk, snap snap!

      I don't understand how you could possibly have Stag and Aero Precision in different tiers. The overwhelming majority of people in the firearms community more than likely would consider them to be on par with each other. Neither of which are a bottom tier IMO

      at atlantic tactical they ran a special fn 16.1 inch ar with a flat top for about a grand plus tax ,I bought three and outfitted different optics to match my shooting styles ,each holds an inch and a half at 300 yards ,now that's a deal worth getting.all but one got an acog .it got a vortex strike eagle 1x8 instead.

      Dumb question. Is it OK to mix the manufactures between up and lower? I just bought an Anderson lower. Can I use another company’s upper?

      March 27, 2018 4:47 pm
      • David

        For an AR-15 yes it is fine. The vast majority of manufacturers all use the same mil-spec standard as everyone else. There are a couple of companies out there that make a weird pattern that isn't mil-spec, but those are very rare, cost an outrageous amount, and comes with lots of warning labels about how they aren't standard.

        All of the manufacturers we looked at in this article all make standard mil-spec uppers that can attach to any standard lower with no worries.

        Personally, I highly recommend Aero.

      Two other great budget uppers are diamondback and CBC industries. I was weary of diamondback as they’re not known to make the greatest pistols, but I’ve already put 1000rds through one and have never had an issue and it’s extremely accurate. I’ve never personally shot a CBC upper but from the reviews they get they seem pretty nice. Both start around $200 with a large variety of uppers on both websites.

      February 21, 2018 12:57 pm
      • Kc p

        I have a CBC upper mounted to a Anderson lower excellent fit and my 16'' 1/7 twist 556 upper is as reliable and accurate as you can ask for regardless of the price at 200 yards I can shoot the cap off of a milk jug every shot it runs steel case tula ammo without an issue and brass runs great the customer service is prompt and they keep you informed on the status of your order unlike the horror stories I've read about from other companies I hope this helps more people decide to exercise they're 2nd amendment rights responsibly

      Eric i always enjoy your articles but I don’t know how lon it’s been since you got a palmetto state armory upper but I have ordered 3 in last 6 months using their deal of the day and they to me are better than most of the middle group you mentioned. I have a DD AR and they don’t compare but I’ve had zero problems and great groups with all of them. Most are what they call blemishes and they usually have a little scratch on the rail or a slight color defect that I’m not sure most could tell if they don’t look for it and all 3 have had stainless free float barrels and the most I paid was $249 because they are blemishes one is perfect because it has a paint chip right where my optic sits. And at that price I was able to put eotech on all. I know this is about uppers but today they have a 5th gen glock 26 and 3 lowers for $599 if you wait and catch the uppers you want you can get 4 guns for under $1200 bucks and the quality of uppers have been great. I’m thinki of pulling plug on the Glock and 3 lower deal and test them out.

        I agree about PSA. I bought an 18" stainless upper in .223 Wylde and mated it to a Ruger lower. It has been an outstanding build. The upper arrived in about a week and was just as advertised. I have been very impressed.

        April 14, 2018 5:21 pm
    • Robert

      JSE surplus is a great place for a large variety of complete uppers. They allowed me to customize the 4 I bought from them. Delton also has a really cool customizable section. There are only 3 upper receiver manufactures and all make them to mill spec. Its the barrel you want to pay attention to. I prefer mid-length gas system. it shoots smoother and tends to be more reliable for extraction. Most barrels are 16" why not get the most out of it.

      I'd like to suggest very decently priced and good quality uppers by Karri's Guns. I bought a 10.5" 5.56 upper and haven't regretted it.

      September 2, 2017 3:41 pm
    • 10mm Jesus

      For the guy that asked about building a 223 Wylde vs 223/5.56. Do not,I repeat do not go with the Wylde as a first timer in ar's. You will regret it and won't be with it long before you end up swapping uppers. My recommendation to anyone entering the world of ar's, build a basic 5.56/.223 then after you are comfortable get a 300 blk upper. 90 percent of the stuff on this list is the same. You learn after years of building that just about every lower is the same. Unless you are looking for a specific logo, custom serial number or a cool feature that a lower may have, all lowers are made by the same three or four companies before being sent to get the premium laden logo attached. Don't worry about building a cool looking gun your first time out. I see guys all the time waste time and money building a pretty gun that doesn't work or shoot for schitt. Make sure any lower you buy is marked multi caliber and listed as a pistol/ rifle lower on your form, that way you can build a formless SBR without the nitpicking. Sigbrace, sigbrace, sigbrace, is all I will say to end this.

      July 30, 2017 8:16 am
      • Chipss

        I would be careful about the way you say this, if your intentions are getting around an sbr tax stamp, your breaking the law, and that is how the law is wrote, you must build a pistol, from a reciver that has never been a rifle, does not matter what the new reciver that has never been a rifle is marked.
        Just saying!

        September 11, 2017 6:02 pm
        • TxProud

          A stripped lower should always be classified as "other", it's the final assembly that determines rifle or pistol. Caliber does not matter on the lower receiver, but very much matters on the barrel.

          Do no assemble a rifle with a barrel under 16" without a stamp in hand.

          December 28, 2017 12:57 am

      wait? what? Putting PSA in the same leage as Olympic arms and RRA? what the literal F??? and putting Anderson above them in Mid tier? psa has SOME cheap stuff (their PTAC line), but their freedom is as good as any in the mid tier line, maybe better, while their premium line almost rivals BCM (almost, not quite)...

          experience. I have multiple guns from BCM, Colt, PSA, Aero (only one Aero at the moment though) and guess what. the PSA Freedom and CHF stuff that has been coming out the last 2 years are seriously good shit. Especially the NEW freedom line (in the last 8 months) when they switched to 4150 CMV barrels and all nitride/melonite as they ditched most of their phosphate stuff. BCM is good shit and imo deserves the higher tier, but their difference between PSA is more in fit and finish vs. actual performance.

          July 31, 2017 2:18 pm
          • Mike Edwards

            it won't let me edit, sorry.

            and my argument is not that BCM and PSA should be ranked equally, but that putting PSA in the same league as Olympic Arms, DPMS and Delton is ridiculous. Especially when he puts ANDERSON (the king of uber cheap ARs) in the mid tier with Aero and the like.

            July 31, 2017 2:21 pm
            • Shane

              Agree 100% late reading this but I’ve bought 3 PSA uppers in last 3 months and all were the freedom with blemish on them and most can’t find the blemish it’s usually a little color difference or paint chip on the rail. I have a DD and they not in that group but I have no problem taking them out plus it gives me little extra to put in optics.

      Hi Eric. I was thinking of trying to build a 5.56 rifle and I had read other articles about anderson lowers being very good quality. I was wondering if it would be a good idea to put a Aero M4E1 16″ upper onto an anderson lower or whether aero percision ( or any other brand for that matter within that price range) Would Be a better choice. This would be my first ar build. Thank you so much for the information on the article it has helped me immensely.

      May 24, 2017 10:25 pm
    • Tony Wendice

      A few thoughts: (1) Since Olympic has gone out of business, it would make sense to remove their products from your listing. (2) Since "USSOCOM Selects M-Lok For Weapon Programs" (google it), the KeyMod platform is pretty much dead. Everyone wants milspec, which is now M-Lok. (3) Why the continuing inclusion of quad rails, which are heavy, ungainly, and often have sharp edges? The best rail design I've seen lately is the ALG Defense EMR v1, which is round-ish, light, smooth, and lets you attach M-Lok accessories anywhere you want. All I want on my rifle is a light and an optic, so I don't see the point of the full-length M1913 rail along the top, either. Not trying to start a fight or troll, just offering some suggestions along the line of "light and simple is better."

    • ERIC

      I just finished a build (kind of a Frankenbuild) with Mega Arms forged upper and lower, UTG Slim Pro handguard, and 16" Ballistic Advantage Hanson Series 1:8 barrel in QPQ finish. The Mega receivers are absolutely tight and well finished. Had to heat the upper to insert the barrel, but I understand this is a good thing for accuracy. First time out, after sighting in the run of the mill Magpul irons, I shot a 20 round grouping the size of a plum at 50 yards. Recommend all of the above parts.

      For the complete aero precision upper do you recommend the pencil profile or m4 profile? 16" mid length gas tube. Just for a good all around gun.

      March 28, 2017 6:01 am
      • Eric Hung

        I like the pencil profiles for weight reduction. Unless you plan on shooting lots of rounds really quickly you won't really see a difference in groups.

        April 5, 2017 4:28 pm
        • Agartha

          Yeah Pew is asinine for saying the "Standard barrel profile: not the Enhanced Light Weight so it's more balanced and has better cooling” This is absurd. The standard Gov profile sucks and everyone knows it’s inferior to modern barrel profiles. The ELW and EMW have a modern taper and will be better at handling and more balanced. Even BCM themselves says that their enhanced profile barrels have "Continuous taper designed for optimal weight, balance, and performance. Tapered profile out front, for easier maneuverability." It's why modern taper profile barrels like the Criterion CORE, BA Hanson, Faxon Gunner, and BCM ELW and EMW profiles exist, just to name a few. Everyone in the industry knows that these are better than a standard gov profile. It makes absolutely no sense why the author would say the opposite, it's just flat out wrong.

      Do you see any negatives going with the 18" wylde upper over the 16" mid length upper by Aero Precision? Other than it being 2" longer, I like the added accuracy it will provide for farther distance.

      February 24, 2017 9:17 pm
      • Eric Hung

        It'll just be longer and heavier...but give you slightly more velocity for farther distances.

          I'm building my very first AR based on your website recommendations of the Aero Precision. For a first time owner of an AR, which barrel length would you recommend? Thank you for your website and taking the time to reply.

          February 25, 2017 9:14 pm

            Hey Grayden, I like 16" for a good mix between velocity and maneuverability. Plus, you can change up muzzle devices without dealing with permanent attachment.

            • Grayden

              Ok 16" it is thank you Eric! However, would you opt for the .223 wylde mid length over the 5.56 mid-length for $25 more? Sorry for all the newbie questions but I really value your opinion in owning my first AR. Thank you again Eric!

              Hey Grayden, I'd say it's based on if you're looking at slightly more accuracy go for the wylde (if you're reloading, really make sure your rounds are in spec, I learned the hard way), but for general shooting go for the 5.56.

      I'm glad to see you included the YHM Black Diamond in the top tier. I did my first build 6 months ago and that is the upper I chose to go with. I have to say it has incredible accuracy. I used top tier products all through the build from a Magpul UBR stock, a Geissele SD3G trigger, a Seekins Precision SBA15 lower to a Steiner T5Xi 1-5x24mm scope. Beast of a build I'll tell you what. I'm glad to see a review that makes an honest assessment on the hierarchy of uppers. Also it reinforces my opinion that I made a good decision in trusting YHM ;)

      Eric, was wondering if you could break these out also by whether they are gas impingement or piston driven?
      Thanks

        Hi Matt, thanks for the tip...I believe they are all direct impingement. But I'll look into adding piston ones too.

      Eric,

      You mention the Black Diamond "16 from Yankee Hill but I did not see Yankee Hill listed in your mfg. rundown. Where do you list the Yankee Hill products?

      Thanks

        Hey Ricky, thanks for picking that up. I added them to my primary AR-15 article but forgot them in the upper assemblies one.

      I know chrome lined barrels are generally less accurate than their stainless steel counterparts, but Im looking for an 18in chrome lined barrel so I don't have to worry about corrosion. Do you have any suggestions?

      Anderson over Bushmaster? XM15 bare bones lower is 350$ Rainier is top shelf as well. Actually, that whole classification of brands is way off. I enjoyed the read, however you putting an FNH as a "mid-tier" weapon is quite laughable. Have you ever touched any rifle made by FNH? I think you would like it! ☺

        Hi Connor, thanks for the comments. Hope to try out some FNH rifles soon!

        249 SAW, 240B, 50 cal, most barrels in the m4 we used in the army. All FNH. Yeah I'd say their top teir indeed
