How We Tested the Best AR-15 Pistols
For this article, we gathered a bunch of AR-15 pistols we've personally shot, reviewed, and owned here at Pew Pew Tactical. The entire Pew Pew Tactical team, as well as freelance writers, contributed to this review to offer different opinions based on ergonomics, size, and experience.
For guns we have reviews on, we've linked those so you can read more.
Every review handgun undergoes a strict testing protocol that requires a minimum of 500 rounds of both FMJ and JHP ammo through it at 5 and 7 yards.
Meanwhile, every review rifle undergoes 500 rounds of practice ammo and heavier match-grade ammo at 50 and 100 yards with a 5-25x scope (unless otherwise noted). We require all AR-15s to be tested with at least 3 magazines to assess compatibility, and we use a Lyman Digital Trigger Gauge to measure the average trigger pull for all guns.
Best AR-15 Pistols
1. Daniel Defense DDM4 PDW - Best Overall
Pros
- Super compact
- Great build quality
- Fun to shoot
Cons
- Expensive
Specs
- Caliber: .300 BLK
- Action: Semi-automatic, direct impingement
- Capacity: 30+1
- Barrel Length: 7"
- Overall Length: 21-24.8"
- Weight: 5.7 lbs
Really, anything from Daniel Defense is a solid buy, but the DDM4 PDW in .300 Blk is particularly awesome.
Rolling with a 7-inch barrel and an overall length of barely 20-inches, this is an incredibly small AR-15. It comes with all of the ergonomics that you would want from Daniel Defense, and that really helps make it feel like a much larger firearm.
From the linear compensator, to the hand stop, to the PDW brace, Daniel Defense makes sure to include everything that a high-end AR pistol should have.
Johnny took it out to the range and has the full review for you, but the short version is that this is one of the best AR pistols on the market.

2. Palmetto State Armory AR-15 Pistols - Best Budget
Pros
- Affordable
- Great bang for the buck
- Lots of configurations
Cons
- Not always in stock
Specs
- Caliber: 5.56 NATO
- Action: Semi-automatic, direct impingement
- Capacity: 30+1
- Barrel Length: 7-12"
- Overall Length: N/A
- Weight: N/A
PSA is well known for offering many configurations based on barrel length, caliber, and brace options.
Come up with a combination, and they most likely have an AR-15 pistol at a shockingly low price.
Here's our full review of their 7.5-inch and 10.5-inch uppers. Complete with our thoughts on fit, feel, reliability, shootability, accuracy, and more.
Barrel lengths range from seven to 12 inches, with lots of handguard and brace options. We love their 5.56 NATO pistols, but PSA also makes other variants, including .300 BLK and 7.62x39.

3. Bravo Company Manufacturing Recce-11 MCMR - Best Value
Pros
- High-quality parts
- Excellent craftsmanship
- Rock-solid reliability
Cons
- Frequently out of stock
Specs
- Caliber: 5.56 NATO, .300 BLK
- Action: Semi-automatic, direct impingement
- Capacity: 30+1
- Barrel Length: 9-12.5"
- Overall Length: 25-28.5"
- Weight: 4.9-5.7 lbs
Bravo Company Manufacturing has a solid reputation for building fighting rifles. In our testing, that's held up.
The Recce series takes lessons from experienced warfighters and puts them into an AR-15 that's tough, accurate, and chews up any ammo you feed it. The carbine-length version is one of our all-time favorite AR-15s.
This pistol-length version has an 11.5-inch barrel (hence Recce-11), an M-LOK handguard (MCMR in BCM-speak), and a bare buffer tube so you can mount whichever brace you want.
These AR-15 pistols can be really tricky to find in stock, so pounce on one if you see it.

4. Sig Sauer MCX Rattler - Most Compact
Pros
- Incredibly compact
- Super lightweight
- Good ergonomics
Cons
- Struggles to cycle subsonic ammunition without a suppressor
- Expensive
Specs
- Caliber: 5.56 NATO, .300 BLK, 7.62x39
- Action: Semi-automatic, piston
- Capacity: 30+1
- Barrel Length: 5.5"
- Overall Length: 17" (folded)
- Weight: 5.1 lbs
Some of you are shouting at your screen that you want a smaller AR-15 pistol -- the smallest one possible. If that's you, it doesn't get better than the Sig Sauer MCX Rattler.
It's super compact, easily concealable, and disappears inside an off-body carry bag when you're on the go. It does bring a little extra "oomph" in the recoil department, but the Rattler was accurate during our testing.
How about reliability?
Our Rattler struggled with subsonic ammo when shooting without a suppressor (suppressors increase back pressure, which helps light loads cycle better). However, it ate more powerful supersonic ammo like a champ.
Moral of the story: run some ammo through it and get a feel for what it prefers before staging it as a home defense firearm. Actually, that goes for any firearm.
The Rattler is not cheap. But if you're willing to spend the money, it's fantastic PDW-sized AR-15 pistol for your home, vehicle, or backpack.

How to Pick the Best AR-15 Pistol
Aside from finding an AR-15 pistol that fits your budget, there are a few factors you need to consider.
Caliber
You have options here. I would first determine your primary use. Is this going to be a range toy, home defense weapon, truck gun, or hog hunter?
Popular AR-15 pistol cartridges include 5.56 NATO, .300 Blackout, and (to a lesser degree) 9mm and 7.62x39.
The most common choice is 5.56 NATO. It's a great go-to if you’re not exactly sure which one to pick or want this to be a multi-use gun. Ammo is not too expensive, and finding parts is a piece of cake.
If you want to shoot with a suppressor, .300 Blackout is an excellent choice. It stuffs a 7.62 NATO bullet into a 5.56 NATO case, which keeps muzzle velocity down and keeps it compatible with a bunch of standard parts because the cartridge's rim and overall length is the same as 5.56 NATO.
Got an opinion? Weigh in on the .300 Blackout vs. 5.56 NATO debate!
If you already own a 9mm handgun and want to be able to swap mags, consider buying a pistol-caliber AR-15. You'll have to make sure it accepts the magazines you already use (Glock mags are the most common), but this can be a way to save some money and get a super fun AR-15.
Not many people opt for 7.62x39, but the Soviet-era Russian cartridge is actually fairly similar to .300 BLK in performance. It's definitely a good way to spice up your collection, and might help you save on ammo depending on which way the market is swinging when you're ready to buy.
Barrel Length
Ask an AR nut the minimum barrel length for 5.56 NATO needs or what length is best for .300 BLK, and you'll get plenty of hot opinions. Without getting into that debate, here are a few of the most common barrel lengths explained.
Many shooters prefer an 11.5-inch barrel for an AR-15 pistol. It's a pretty safe bet for 5.56 NATO because it it maintains decent muzzle velocity and barrels are common. A 10- or 11-inch rail pairs perfectly with an 11.5-inch barrel.
A lot of SOCOM rifles use 10.3- and 10.5-inch barrels, and these lengths have been working their way into the civilian market as well. I personally have a 10.5-inch barrel in 5.56 NATO and love it. Yes, there are some fireballs, and it is quite loud, but it's a comfortable length for me and allows for a lightweight build -- especially if you're going to add a suppressor onto the end.
One of the advantages of .300 BLK is the ability to run a shorter barrel without sacrificing ballistic performance. You can comfortably go all the way down to 9 inches!
Super short barrels, like 5.5 inches, are most common on pistol-caliber AR-15 pistols. They're great for 9mm, although the Sig Sauer MCX Rattler uses a 5.5-inch barrel with .300 Blackout.
Pistol Brace
A pistol brace is what makes an AR-15 a pistol rather than an SBR. There are several types of braces out there, ranging from the stable SB Tactical SBA5 to a simple foam pad on the end of a buffer tube.
Choosing the right brace is a matter of personal preference. Do you care more about agility or stability?
Handguard and Rails
Every AR-15 pistol has a handguard covering the barrel and gas system, but they're not all the same.
Pay attention to how each rail interfaces with accessories. You'll see terms like Picatinny, M-LOK, and KeyMod. These all work, but they'll dictate which accessories are compatible with your AR-15 pistol.
If you don't know which is which, you can't go wrong with a Picatinny rail in the 12-o'clock position and M-LOK everywhere else.
How to Build an AR-15 Pistol
Whether you're building an AR-15 pistol from scratch or upgrading one you already own, you're eventually going to need a few parts and accessories.
We have tons of resources on the Best Upper Receivers, Best Bolt Carrier Groups, Best Charging Handles, Best Lower Receivers, How to Build an AR-15 Lower Receiver, and lots more.
While you're here, though, these are a some of our favorites for building or modifying an AR-15 pistol.
Palmetto State Armory Complete Lower Receiver
Palmetto State Armory offers a complete AR-15 lower equipped with an SB Tactical SBA3 brace. This lower is ready to pair with an AR upper to give you a full AR pistol.
It comes with a Magpul grip and trigger guard as well as the Enhanced Polished Trigger Group (EPT).
It features the SB Tactical SBA3 Adjustable brace at a decent price point under $250. While this isn't a complete set-up out of the box, if you have a spare upper lying around or just want something in stock at the moment, this is your best bet.
Timney Competition Trigger
Dollar for dollar, you'll struggle to find a better upgrade for a factory AR-15 pistol than a better trigger. This single-stage trigger from Timney is a night-and-day difference from mil-spec triggers and it's priced fairly affordably, as competition triggers go.
Hungry for more? Read up on our guide to the Best AR-15 Triggers!
Magpul MOE+ Grip
Another great way to upgrade a basic AR-15 lower is to switch out the pistol grip. Not sure where to start? We love all the options from Magpul.
Magpul's MOE grips are easier to hold than a standard A2-style grip, create a more comfortable angle for your wrist, and have a storage cubby for things like spare optic and light batteries.
Best of all, they're super inexpensive!
If you want more options, check out our guide to the Best AR-15 Grips.
SB Tactical SBA5
SB Tactical is the original inventor of the stabilizing brace, so you know they’ve got it figured out by the fifth generation of SBA braces.
We love the latest version, the SBA5. It's nice and stable while maintaining the essential braced status of an AR-15 pistol.
They didn't reinvent the SBA4 because the didn't have to. This is a natural evolution and a fantastic brace.
Daniel Defense MK18 Upper Receiver
If you like the look of the Daniel Defense MK18 , the upper is available on its own for pistol builds. The 10.3-inch barrel is a really versatile size that we found fun to shoot suppressed or unsuppressed.
We took the MK18 to a shoot house and ran more than 2,000 rounds through it in a matter of days. It held up well, shot accurately, and ran reliably.
If you want to learn more, we have a MK18 review and video!
Palmetto State Armory 10.5" AR-15 Upper Receiver
Yep, Palmetto State Armory makes some very value-focused AR-15 pistols and you can get the upper and lower receivers separately.
There are lots of configurations to choose from. Find your ideal combination of barrel length, handguard, and muzzle device. Some even include backup iron sights.
These will put you well on your way to a rockin' pistol with plenty of money left over for an optic, weapon light, and training ammo.
Ballistic Advantage Barrels
Do you want to pick the specific barrel for your AR-15 pistol? You can!
You really can’t go wrong here. Ballistic Advantage has just about every length and caliber combination we can think of. If you have something specific in mind, this is a great place to start.
We've used their barrels before for other builds and loved them. Take a look at the full Ballistic Advantage Barrel Review to see what I mean.
Faxon Firearms Barrels
Faxon Firearms makes high-end components for lots of firearms, including AR-15 pistols.
This is where I purchased my barrel -- partially because it happened to be on a great sale, but also because it had great reviews (including two from Pew Pew Tactical).
Faxon builds these barrels in-house with high quality control standards, and the prices are reasonable. From their Glock Barrels to pencil-profile AR-15 Barrels, we're fans.
Holosun 510C
Holosun always offers a great value, and we're big fans of the 510C. It's rugged, effective, and has a great reticle. There's even a solar panel to extend battery life!
Aimpoint Patrol Rifle Optic
Good news, you can get an Aimpoint optic for less money than you might think!
The Aimpoint PRO runs for three years on a single battery and is famously tough. The dot is clearer than you can imagine and makes target acquisition extremely simple. This is one of the best AR red dots out there, as long as you can stomach the price.
Need to know more? Read our complete Aimpoint PRO review!
EOTech EXPS3-2
In simple terms, this optic kicks ass. EOTech is one of the most respected names in optics and the EXPS3 lives up to its hype.
This version, the EXPS3-2 features a multi reticle with an outer ring and two aiming dots to account for different distances.
You can learn more about EOTech and holographic sights in our roundup of the Best EOTech Holographic Sight Models.
Trijicon ACOG
Want an optic that's not just tough, but battle-tested? You need a Trijicon ACOG!
This little ACOG is magnified to just 1.5-power. That gives you a slight edge without severely limiting close-quarters performance. It's still an ACOG, though, so it's just about bombproof (seriously, some of these have survived IED blasts overseas).
We love the durability, reticle, and illumination that runs off sunlight. Sure, it's expensive, but it's a combat optic!
Vortex Viper PST Gen II 1-6x24
If you’re looking to shoot out to 300 yards or so, the Vortex Viper PST 1-6x24 Gen II is a great choice and a versatile optic. While it will add quite a bit of weight to an AR pistol, the extra magnification will give you more confidence at longer distances.
Take a look at our in-depth and hands-on review of the Vortex PST in our Best 1-6x Optics article. For everything else, we have our super comprehensive Best AR-15 Scopes & Optics Guide.
