Our Dream AR-15 Builds

The military style appearance of many AR firearms has fed the controversy.
We sat down recently to brainstorm the AR's we'd build if money, time, and other constraints were thrown out the window. These are the guns we came up with. Take a look, and let us know what you think!

    So, if you’re like us, you’ve probably spent some time sitting around daydreaming about what your ideal AR would be.  No?  Just us? Well anyway, here are the AR’s we would build if money wasn’t any object, and we could get our hands on any parts.  Hopefully, something in here will inspire you in your own builds. Let’s get to it. Note: We will be updating this list until we have something from all the writer’s dream setups, so be sure to check back in!

    Upper and Lower Receiver: 2055 LR Enlightened AR-15 Receiver Set by V Seven

    The 2055 LR Enlightened Receiver Set gives you a high-quality and mighty fine looking upper and lower receiver for your AR-15.  I opted to go with the set rather than selecting a different upper and lower receiver because I really like the way this product is designed.  
    V Seven 2055 AR-15 Receiver Set
    V Seven 2055 AR-15 Receiver Set
    For starters, it’s made from a 2055 lithium and aluminum alloy that outperforms 7075 T6 aluminum in virtually every way – it’s lighter, more durable, and better protected against corrosion than its counterpart.   It also has a combined weight of 12.2 ounces (5.8oz for the upper receiver and 6.4oz for the lower), making it nice and lightweight.

    Lower Parts Kit: AR-15 with Ambi Selector by CMMG

    When it comes to a LPK, all I’m really looking for is quality components made by a reputable company – and you can’t get more reputable than CMMG.

    Their AR-15 LPK comes with all of the springs, pins, and knickknacks you need to get your lower receiver up and running.  The kit also comes with a pistol grip and trigger, and in my opinion, CMMG make some pretty good triggers.  But since this is my dream AR-15, we’re going to save this trigger for a replacement. And I’m always a fan of having an ambi safety selector, so be sure to get this add-on.

    Trigger System: Drop-in Elftmann Match Trigger by ELF

    ELF has a good reputation for making quality competition triggers.  Regardless of what you plan on using your AR-15 for, this trigger system will give you a smooth, jerk-free pull every time.

    ELF triggers minimize overtravel and trigger reset, which is great for anyone who’s looking to squeeze off a few rounds rapidly.  But what I really like about this trigger system is the added safety that it provides.  The trigger system’s special design prevents it from being discharged on impact, turning your AR-15 into a drop-safe gun.

    Barrel: AR-15 Carbon Fiber Barrel with 2” Gas Seat by Christensen Arms

    When it comes to carbon fiber barrels, there are two things that you need to know: they perform brilliantly and they’re ridiculously expensive.

    But carbon fiber barrels are worth every penny to those who can afford spending so much on a barrel.  They give you top precision and accuracy like their stainless steel counterparts, but are way more durable.  And when it comes to carbon fiber barrels, Christensen Arms knows a thing or two –they did develop the first carbon fiber rifle barrel, after all. This barrel comes with an aluminum .936 gas block and is available in a variety of lengths and calibers, including the .204 Ruger and the 6.5 Grendel.  But for this AR-15, I prefer to stick to the basics and go with 5.56 NATO at 16”.

    Handguard: Midwest Industries G3 ML

    It’s not the fanciest handguard out there, but it’s easy to install and does everything you need it to.  It’s also incredibly lightweight, weighing only 8.8oz.

    Bolt Carrier Group: Titanium Bolt Carrier Group by SCT Solutions 

    Titanium BCGs aren’t cheap by any stretch of the imagination, but they’re great for when you’re looking for strength, durability, and something significantly lighter than steel.
    Titanium BCG SCT
    Titanium BCG SCT
    This BCG comes highly recommended thanks to its top-notch craftsmanship and promises smoother cycling and less recoil than some of the other BGCs on the market.  Plus, another great thing about this product and other titanium BCGs is that you don’t have to restrict yourself to adjustable gas systems, like you would with an aluminum BCG. Still, this little component does cost a pretty penny.  

    Charging Handle: AR-15 Raptor Charging Handle 5.56 by Radian Weapons 

    I like this charging handle because it’s ambidextrous and ergonomically designed.  More than just an aluminum rod, this charging handle has a perfectly angled grip that makes it easy to grab ahold up, regardless of whether you’re working with your right or left hand.

    Despite its unforgiving sticker price, the Aimpoint Patrol Rifle Optic is a solid accessory to any AR-15.  It’s water resistant, has a long battery life, and can handle extreme temperatures – that already places it a notch above EOTech’s holographic sights in my book (still, I think they’re also good).   Plus, the optic works clearly in both day and night and is compatible with night vision devices and Aimpoint’s 3X magnifier.

    Offset Backup Iron Sights by Ade Advanced 

    Personally, I believe that it’s always a good idea to have a good set of BUIS in case your optic breaks or malfunctions.

    Putting Together my Dream Gun

    As you can see, there’s not anything flashy or exceptional about my piece.  Some AR-15s are built to go, others are built for show – and I prefer mine to be ready to go the distance! With a ~$2600 price tag, it’s probably one of the more expensive range guns that I’d own.  But I do think that it’d be a great gun to spend a lot of time shooting.  Not only would it be fun to spend the weekends shooting, it should be able to withstand heavy use with minimal issues.

    Upper: Critical Capabilities AR-15 9mm Upper Receiver

    We’ll start with the upper receiver.  The upper really tells you what the gun is really going to be.  My AR is starting with a Critical Capabilities AR-15 9mm upper.  This gun is outfitted with a short 5.5-inch barrel.

    You see my gun is going to be a super small and easy to carry AR-15 pistol, chambered in 9mm.  The Critical Capabilities upper receiver is a flat top upper and comes with a 4-inch M-Lok rail.  The upper is already built and ready to go, all you need is a charging handle and a bolt carrier group. Of course, the upper is in 9mm and can’t exactly be called “Mil Spec,’’ but it shares several Mil Spec features.  This includes being a forged 7075-T6 upper, a type 3 anodization, and a chrome moly nitride treated barrel. It’s simple, lightweight, small, and perfect for CQB.

    Lower: JP Enterprises GMR-15 9mm Lower Receiver

    For the lower I’d go with the always fantastic JP Enterprises GMR-15 9mm lower.  It takes Glock 9mm magazines and is a billet lower.  It looks fantastic and the billeted cuts will match well with the M-Lok rail system on the upper.

    If you don’t look cool what’s the point?  JP Enterprises makes great gear and this lower is a great option for a 9mm build.

    Brace: Sig Sauer SBX

    So we have to attach something to the rear of the lower right?  You can go SBR, but keeping it a pistol is much easier.  A brace keeps the gun a pistol but makes it a little easier to stabilize.

    By stabilize we mean strapping the gun to your forearm…or maybe putting it against your shoulder.  The ATF has come down and said, “Hey, that’s cool, you know, don’t modify it to make it easier to shoulder in any way.” There are lots of braces out there, but the SIG Sauer SBX is perfect for this build. It’s lighter and smaller than the original SB 15 brace, and is a bit better suited for my plan to with the brace and buffer tube. It’s not the cheapest brace, but it’s one of the best.

    Buffer Tube: Brownells AR-15 Pistol Buffer Tube

    Not much to say here.  Just a simple, completely smooth tube.  It’s a pistol buffer tube and needs to be smooth to accommodate the SBX brace.

    Again the buffer needs to be simple.  Sometimes s standard AR buffer will work, but I want perfection.  So, we are going with an Angstadt Arms LLC 9mm buffer with the appropriate spring.  With this in the gun you’re guaranteed to get bang after bang out of your gun.

    Now buffer tubes and buffers may not excite you, but the LAW Tactical folding stock adapter should.  This attaches between your gun and buffer tube and gives your AR-15 a folding stock.  You can’t shoot with the stock folded, but this makes it easy to store and even conceal the gun in a bag or box.

    Pantheon Arms Dolos Kit

    The Dolos Kit is a takedown system for the AR rifle.  It installs between your upper receiver and barrel instantly turns your gun into a takedown design.  You can remove or install the barrel and rail system in about 3 seconds.

This system will work with the Critical Capabilities included MLOK rail, and works with almost any standard rail system.

    JP Enterprises BCG

    We used the JP Enterprises lower and now we are going to toss in the JP Enterprises 9mm BCG.  The BCG is even compatible with JP’s super silent capture spring.  It’s important you watch the BCG to the magazine pattern.

    Critical Capabilities LPK

    The bad thing about pistol caliber ARs is that using decked out match triggers is possible, but they can have some issues.  Mil Spec triggers are the go to for reliable function with an AR-15 in 9mm.

    Pistol Grip: Magpul MIAD

    This isn’t the fanciest of grips, but it is one of my all-time favorites.  Having the right grip angle on your guns means a lot when it comes to handling your gun.  The right angle can help with maneuverability, reduce fatigue, and shoot a little straighter.

    Optic: Trijicon RMR Dual-Illuminated Sights

    Since it’s my dream build, I want the best miniature red dot on the market, the Trijicon RMR.  This particular model is the dual powered design.  It uses both batteries and light to power it.

    Sights: XS Sight Systems AR-15 Sights

    If you have an optic, but no iron sights you are doing it wrong.  With budget not being a concern, we are going with the XS Sight Systems AR-15 sights.  This collaboration between XS and Troy has given 24/7 sights.

      I like Brandon's, but I'd get CMMG LPK w/o grip or trigger components. I'd go BCM grip and BCM's KMR handguard. I have the 10" KMR, I personally like the feel of the contour. His upper and lower choice is sweet though. Carbon fiber barrel!?! I WISH!!!

      Ascend Armory 7075 AR15 receiver set.
      Falkor ambi CH.
      BAD ASS.
      BCM or K2+ grip.
      Geissele single stage or S3G, or maybe
      try one of those Hiperfire 24s. I have
      their EDT3 & really like it.
      Magpul SL-S stock or BCM SOPMOD.
      Mlok handguard is a toss-up between a
      few mfgs: Geissele, Radian, ADM, KAC,
      Wilson Combat, DD.
      Some super expensive, fancy, (probably
      carbon fiber) barrel in .223 Wylde. Or
      might go with a different caliber like
      .300 BLK or .224 Valkyrie. 16-18” rifle or
      11.5” for SBR.
      Trijicon 1-8x scope.
      Offset MBUS Pro.
      Any decent nitride HPT/MPI BCG.
      Not sure on muzzle brake. Would want to
      try one I haven’t used yet. But as for
      those I have used, Lantac or VG6. Or
      better yet a Surefire QD brake for
      suppressor.
      A nice cerakote job. After all, money is no
      object, right?


      ...or something like that.
      But that’s just one of many ever evolving dream builds.

      I have only been shooting a few years, long guns more recently, and one of the reasons I like reading this type of article is the awareness it brings of what is possible. For example, my first AR, a Noveske 300 SBR, while being rock solid, is a heavy little beast. So when I went looking for a 556 upper, I went with a light barrel and handguard from BCM. Man that thing is light…to me anyway! But I had no idea carbon fiber-based barrels are available until reading this article. I am older so have more disposable dollars at this point in my life and am admittedly a high-tech nerd so I wonder how the carbon barrels manage heat. I did notice that it does not take much shooting before my light barrel starts smoking all over! I have read that after a barrel "overheats" you lose some accuracy. I am not skilled enough yet to notice and have not tested this yet. I would appreciate your thoughts on that.

      Thanks, Mark

        Hey Mark, we did a review of Faxon's pencil barrel that highlights some of the groups opening up (again, it's only a little at 100 yards so unless you're shooting very far distances or in a marksmanship competition...it likely won't matter).
