best ar pistols - cover

With the AR-15 commonly described as “America’s Rifle,” the more recently introduced pistol variant of the iconic firearm is rapidly gaining attention, making selecting a good one from the now-crowded field a challenge.

Pistol ARs give you more mobility, a lighter package, and an arguably more capable close-quarters platform than the traditional AR rifle. There’s no single best option, so what you’ll want will depend on how you intend to use the gun, your budget, and what you’re ultimately looking for in your new pistola. 

Nonetheless, if you keep a few things in mind, the choices soon become easy.

No old-school SB15 brace here

Sig can be credited with making the AR pistol mainstream today their top-shelf model is the MPX Canebrake piston gun while the people’s champ is the more practical M400 Tread which comes standard with the more modern Shockwave Blade multi-position brace rather than the now old-school SB15.

While Colt popularized the AR-15, it was FN that ran with the design and has been a key government supplier of first the M16A4 and then the M4 for decades.

Also, while Colt hasn’t dipped their toe into the AR pistol pool, FN has embraced it and has been marketing a 10.5-inch chrome-lined model with an SBX-K brace for the past few years.

If the military was looking to buy crates of semi-auto AR pistols, they would probably call FN direct.

AR Pistol History

The concept of the first consumer AR-15 pistol perhaps goes back to the Gwinn/Bushmaster Armpistol of 1972.

While the AR-15 series of carbines, a product of Fairchild Aircraft’s ArmaLite subsidiary, have been around since 1957, the AR-style handgun is a much more recent animal. In fact, the AR-15 existed for three decades before a semi-practical version of the gun in pistol format first gained real traction on the consumer market. 

The original circa 1963 Colt SP-1/R6000, with its 20-inch barrel and 40-inch overall length, almost was instantly supplemented by the R6001 Carbine with a shorter 16-inch barrel.

Likewise, the military sliced their standard 39.5-inch M16 rifle first to the more compact Vietnam-era XM177E1, then to the M4 which used both a shorter barrel and a collapsible buttstock, to drop the length down to 29.5-inches.

U.S. ASSAULT RIFLE SMG GAU

 

While the Gwinn/Bushmaster 5.56mm NATO “Armpistol,” a compact 20-inch-long bullpup handgun that utilized some AR-15 parts, was around back in the early 1970s, its internals were pretty far and away from being that of the Eugene Stoner’s original ArmaLite work.

By 1986, the Australian Automatic Arms Corp, based in Tasmania, was exporting their SAP pistol to the U.S., an AR-15-ish handgun with a fiberglass receiver and forearm along with a 10.5-inch barrel.

An American AR Pistol

The first American-made AR pistols debuted in 1993, the Rocky Mountain Arms Patriot and the Olympic Arms OA93, the latter of which going on to live in gun culture forever as being used the same year by William Dafoe as CIA super spook John Clark in the film Clear and Present Danger.

Unfortunately, the 1994 Federal Assault Weapon Ban largely froze commercial AR-15 development for a decade from 1994 until it expired in 2004.

Expiration of the Federal Ban Helps the Pistol Market

However, once the federal ban went the way of the dinosaurs, the market began to voraciously expand, with the 20 or so AR-15 rifle makers in 2005 growing to over 200 today.

Still, while Olympic Arms rebooted their OA-93 and new pistols such as the Bushmaster Carbon 15P and Hesse HAR-15 began to circulate, it was the initiative of firearms giant Sig Sauer that broke the mold and took the AR-15 handgun mainstream by introducing their P556 in 2009, later adding their P516 to the lineup in 2011. 

Then, Sig introduced a serious game-changer.

AR Pistol Braces

In 2013, Sig Sauer debuted their PM400 series AR-15 pistol complete with the SIGTac SB15 Stabilizing Brace billed as being able to “Dramatically improve the single-handed performance of buffer tube equipped pistols.”

Not a Stock, No Paperwork

Patented by Alessandro Bosco of SB-Tactical, the Sig Brace was blessed by the ATF as not being legally a “stock” thus avoiding changing such handguns it was attached to into a short-barreled rifle, which would require a tax stamp and NFA (National Firearms Act) paperwork.

Such arm braces and follow-on models like the KAK Blade, SBA3, Gearhead Tailhook, and others have continued to evolve the AR-15 pistol market, allowing essentially a “poor man’s SBR” without the hassles of extra ATF paperwork or crossing any National Firearms Act boundaries.

The Brace Market Explodes

The appeal of these new braced pistols kicked off a surge in demand and by 2019 more than 50 gun makers were cranking out an AR-pattern handgun including big names like ArmaLite, Barrett, Daniel Defense, FN and Wilson Combat.

Nonetheless, keep in mind that AR pistols using just a buffer tube padded with just a simple foam sleeve or neoprene sock can still provide a decent cheek weld without having to be further supported except by the hands– while shaving a few inches overall length by not including a brace.

It is a solid shooting method for these guns that can prove very effective with practice but one that too many shooters, used to handling the AR-15 as a rifle and seeking firm shoulder support from a stock, fail to try.

Why an AR pistol?

Although Eugene Stoner’s AR-15 is an excellent platform, with millions of the popular guns in circulation, it is a rifle that is both more than capable of performing in a huge variety of situations and chamberings — from 5.56 NATO to 7.62, .300 Blackout and beyond. 

Beyond cartridge options, it also supports thousands of accessories and modifications — from red dots to flash suppressors, pistol grips, and free-floating handguards. Users have tried to shrink it across its existence to make it more compact and maneuverable in tight spaces, such as when moving through buildings or exiting a vehicle. While not exactly a concealed carry option, these guns pack a lot of performance into a decidedly concealable package.

Mobility

There are two main reasons people tend to like AR-15  pistols. The first is that they’re a compact firearm that is competent both at the range and self-defense applications.

Many folks use AR pistols as their home defense guns, especially when set up with an optic and a suppressor.

Increasingly, folks use them as a truck gun — taking them along in their vehicles. Having an intermediate cartridge in a short package that still offers plenty of room for accessories makes for a tremendously compelling firearm.

The AR-15 pistol, fitted with a rifle caliber barrel as short as 5.5-inches and no provision for a stock, could move into the neighborhood as tight as 17-inches overall– making it able to fit in a backpack or other tight spots.

This factor allows quick use for those not only in dense brush, such as hunting wild hogs, but also for those seeking some fun on the range, a gun easy to carry in the backcountry, or one quick to provide serious home defense at bad-breath distance.

No Hassle

Another big reason people like these firearms is that they get you many benefits of a short-barreled rifle without going through much hassle in terms of paperwork. To get a short-barreled rifle, you have to fill out a form with the ATF and file paperwork on it: the same is true every time you plan to cross state lines with it.

Avoiding this hassle, an AR-15  pistol gets you the same short barrel and most of the same features, typically for a lot less money. The downsides here are that you’re forbidden from attaching a stock or a vertical foregrip to an AR pistol, but for many people, a pistol brace and a hand stop work just fine for their purposes.

What to Look for in a Quality AR Pistol

1. Barrel Length

AR Barrel Lengths
Pistol barrel lengths can vary widley but have performance implications

While in theory AR pistols can have a barrel of almost any length over 4-inches– which is the minimum gas port dwell required to work Stoner’s direct gas impingement action– about the shortest marketed have been 5.5-inches.

The AFT defines a pistol as: A weapon originally designed, made, and intended to fire a projectile (bullet) from one or more barrels when held in one hand, and having (a) a chamber(s) as an integral part(s) of, or permanently aligned with, the bore(s); and (b) a short stock designed to be gripped by one hand and at an angle to and extending below the line of the bore(s).

In short, a one-handed, short-stocked firearm. 

On the opposite end of he spectrum, there have been some downright near-rifle-length pistol models. Subtracting these extremes produces a happy median of between 7.5- and 11-inches, a zone which has proved the most appealing for these handguns, especially as this span allows for a more reliable carbine-length gas port system with a low-profile gas block rather than the shorter and dirtier pistol-length system.

Velocities & Barrel Length

Studies by experts in the firearms field have shown that, while the 5.56mm NATO in most loads will break over 3,000 fps velocity when fired from any barrel length over 14.5-inches, this speed starts to dump rapidly to the point that short barrels just 10-inches long will lose about a fifth of that, running about 2,400 fps.

By the time you chop a barrel down to the 7.5-inch mark, which is about the minimum length that is still practical, you are good to wring 2,000 fps out of standard AR ammo with lower velocity leading to a less gyroscopically stable bullet and lower energy in the bullet when it reaches the target.

Another side effect of shorter barrels is that the stubbier they get, the more powder remains unburnt, which gives the gun a higher uncorking pressure at the muzzle, translating to a bigger and more distracting muzzle blast or fireball.

In short (excuse the pun), the longer the barrel on an AR-15 pistol, the more accurate, useful, and easier to shoot it will be. 

On the other side of the coin, the shorter the barrel, the more the ammunition’s performance envelope will decline, and the user will observe a more pronounced muzzle flash, the latter of which can be smoothed out with muzzle devices such as flash cans or through the use of suppressors.

In the end, the AR-15 pistol offers a lot for the discerning firearms collector and fills a niche that generations of gun buyers have been looking to satisfy. These days, the question is not, “why do I need one?” but more so, “why don’t I have one?”

2. Barrel Profiles

Barrel-profile
Barrels waiting to find a home

Barrels are designed with different profiles, or essentially, metal thickness. A thick profile means the barrel has the same profile (thickness) from end to end.

These barrels are heavier but are also more accurate and take longer to wear down. A thin profile, or pencil profile, is lightweight but may wear out sooner. These can also be referred to as contours. The shape of the barrel may change contours but still perform its duty.

3. Barrel Linings

AR Pistol Barrel Stamp
Barrel markings will tell you a lot about the business end of your pistol

Wearing out a barrel refers to wearing down the linings. This is the rifling of the barrel. The lining takes a real beating when a barrel heats up from extended firing.

Interestingly, just because a thick profile has more material to be more durable, it’s also harder to cool down. Thin profiles heat up faster, but they cool more quickly.

Barrels are formed in three ways: cutting, button rifling, and forging. Cut rifling is when a machine cuts each rifle groove one time. Button rifling is where a plug is forced from one end of the steel blank barrel to the other end.

As it passes through the steel, it creates grooves.

Forging uses a tungsten “negative,” inserted into a steel “blank” as a large machine hammers the steel around the tungsten. This creates a rifling pattern.

4. Bolt Carrier Groups (BCG)

The best part about building or buying an AR pistol is that the BCGs are the same as any standard AR-15 BCG.

The BCG contacts the cartridge & the byproducts of the firing sequence, which means It needs to be cleaned often.

Each component that makes up a BCG is important. The parts include a bolt, ejector, ejector spring, ejector roll pin, extractor, extractor pin, extractor spring, three gas rings, bolt carrier, bolt cam pin, carrier key, two bolt carrier key screws, firing pin, and firing pin retainer pin.

When the trigger is pulled, the firing pin ignites the primer, and the round takes off. The gas is funneled back into the gas key and down into the BCG. The three gas rings create a chamber by blocking off access to the rest of the group.

This forces the bolt carrier back against the recoil spring as the cam pin twists the bolt to let the BCG move rearward. Then it all resets as the cartridge extracts and chambers the next round.

DI vs. Piston Sytems

An AR pistol can be built with direct impingement (DI) or new gas piston technology.

If you’ve never heard of direct impingement, and you own an AR-15, your rifle was most likely built with this system. DI has been tested and proven reliable for years as its the original technology devised by Eugene Stoner.

Take a look at your barrel. There should be a small hole located in the barrel that lines up with the gas tube to direct gas to impinge on the carrier mechanism.

This is what causes gas blowback, but it is how your entire rifle functions. This gas pressure allows the empty cartridge to eject and the next one to seat in the chamber. (This is also why your rifle builds up with carbon).

The gas piston technology is only similar in that the gas is diverted through the barrel, but instead of a gas tube, it’s contained within a cylinder with a piston.

The gas moves this piston which performs the ejection process of the spent brass. The bolt carrier is pushed forward by a spring to close. If you own an AK-47, you most likely have a piston system.

You’re probably thinking, what’s better? Well, that depends on what you want to accomplish with the gun. The DI system is more common, which means parts are easy to find and relatively inexpensive. However, the bolt carrier will heat up and needs to cool down before it can be removed from the rifle. Regular cleanings are also recommended.

The piston gas system keeps the rifle’s action cool, meaning the bolt carrier can be removed and held in your hand immediately after firing. This system does increase recoil and can decrease accuracy, especially with multiple shots fired in succession. Lastly, parts are not interchangeable between piston guns, so if you use this system, it’s wise to buy replacement parts simultaneously for that specific gun.

5. Optics

A red dot or holographic sight makes sense for an AR pistol given they're close-quarters focused.

Optics are a significant consideration.

An AR pistol should have an optic that is easy to pick up and use quickly.

The last thing you want to mount on this gun is a scope.

We’re a little old-fashioned, so a pair of iron sights, preferable a folding set, is a must for us on every AR we own. While you won’t get much in the way of ranged accuracy thanks to the short sight radius on AR pistols, the option to use them is always better than not.

From there, we also highly recommend a micro red dot sight on your AR pistol: magnified optics tend to be a little too bulky for our tastes here, as the point of an AR pistol is to keep things small and compact whenever possible. 

Red dots will be the most advantageous optic to use in close-quarters combat. While not an optic, another consideration is a laser or a laser/light combination. Lasers have to be sighted in just like any other optic but can allow a person to set the laser on an attacker without ever having to look through an optic.

While many defensive situations happen in daylight, many more occur at night. Without an optic, laser, flashlight, or something you can see, aiming will be more difficult in low light.

6. Furniture

Side-by-side Handguards
Handguards provide protection from a hot barrel and give you loads of room to mount accessories.

You must choose a handguard length that makes sense with the length of the barrel you choose. Your hand should never come into contact with or grip your barrel, which is where handguards come in. There are two types of handguards, free-floating and fixed.

A free-floating handguard is directly mounted to the upper receiver. It’s essentially a long tube that never touches the barrel.

The accuracy of a barrel can easily be impacted if anything touches or comes in contact with it while firing. That’s what makes the free-floating handguards so popular. They also can be longer than the length of the gas system when using a low-profile gas block, extended the useful area of the guard.

A fixed handguard is usually not so fixed. These handguards are held in place by the delta ring and the plate behind your front sight post. If there’s any wear on the delta ring, these handguards can tend to move around — and even the smallest bit of movement can impact your ballistics.

When it comes to a rail system, you need to envision your setup before making a choice. If your AR pistol needs an optic on top, a backup optic on one side, a laser on another side with a flashlight, you may need a quad rail system to mount everything on it.

For most free-floating handguards, they use either a Picatinny rail, M-Lok, or Key Mod. These are different designs for mounting hardware. Key Mod looks like keyholes, for example, which is how it got its name. One isn’t necessarily better than the other, so much as your optics, lasers, lights, etc., have to match the rail mounting system to be compatible.

7. Muzzle Devices

AR Pistols - Muzzle Devices
Muzzle brakes & flash hiders are helpful for controlling the AR pistol's tendency towards noise and rowdiness.

Muzzle devices are used for a variety of reasons. They can direct gas outward to decrease blowback and recoil. They can act as flash hiders. A quality muzzle device will direct the gas outward evenly to prevent moving the gun in any one direction, giving the shooter the ability to make a more accurate follow-up shot.

A muzzle brake is more commonly used as a gas diverter and to lower felt recoil. Flash hiders were built to reduce the visible signature while firing by cooling the gases that exit the muzzle.      

8. Triggers

Picking out a trigger is a personal preference and also a skill/safety check. Triggers can come in a two-stage configuration or single stage. A two-stage trigger has two stages – the take-up stage and the wall stage. A single-stage trigger has one consistent pull for the entire trigger pull. Single-stage triggers are used more in competitive landscapes. Because they are so lightly set up, they can cause accidental discharges, especially in high-stress situations.

Again, triggers can also be flat or curved, a personal preference on what feels most natural to you.

9. AR Pistols and the ATF

At any given moment in time, this sentence could become obsolete as the ATF has either tried to or has made laws that affect the legality of AR pistols or their parts.

As mentioned earlier, before ever building or buying an AR pistol, you have to be clear on the legalities of lowers and their respective roles in an AFT-classified “rifle” or “pistol”.

In short, if a lower or receiver was classified as a rifle it cannot be converted to a pistol, but — with a From 1 and $200 — it can be converted into an SBR. 

 10. Users & Uses

If you’ve never had to clear a house with a rifle, you probably don’t know how tough it is to swing a long, heavy barreled rifle in and out of doors, up staircases, and around rooms. AR pistols are a necessity when it comes to law enforcement and military applications. The maneuverability of them is what makes them so popular. They’re also used for defensive situations, and ranged accuracy matters less in close-quarters combat.

As for civilians, AR pistols make great truck and home defense guns. If you don’t want to pepper your house with a shotgun when an intruder breaks in and shoulder a scattergun’s high recoil, an AR pistol should be your weapon of choice.

Types of AR Pistols

5.56mm NATO Pistols

The first are those that come in the standard AR-15  cartridge, the 5.56mm NATO. Out of a 10” barrel, this round is still effective out to about two hundred yards, but the AR pistol’s short barrel does somewhat hinder the cartridge’s performance.

Your AR pistol will likely not be the most accurate long-range gun in your collection, but if you want a close-up weapon, they can be a great option.

PCC/9mm Pistols

Second, and increasingly popular, are those AR pistols that are in calibers other than 5.56mm. The most popular one here is 9mm, often accepting Glock magazines or something similar.

These make excellent suppressor hosts, and many folks use them for self-defense or as their long gun for shooting competitions. One of the primary benefits here is that these can often be planned out to share a magazine with your pistol, which makes logistics and reloading much more straightforward, especially in home defense scenarios.

DI Pistols

Third, most AR 15 pistols will use Eugene Stoner’s original AR design, a direct gas impingement system. While these tend to run a little dirtier than the other gas systems out there, they are immensely reliable with quality ammunition.

In an AR pistol, though, full-powered 5.56mm has a lot of gas left to burn off at the end of a 10” barrel, and a fair bit of it is likely to end up back in the action, which tends to slightly over-gas these pistols. But, with that said, as long as you replace the buffer spring every few years and keep an eye on any excess wear, this is not usually an issue for most users.

Pistol Pistols

Fourthly, some AR pistols run with some variant of a gas-piston system of the type more commonly found in the AK series of rifles. This has one major advantage for pistols: the excess gas gets vented early in the firing sequence and thus does not end up back in the action. It does mean a few different or extra parts to keep an eye on, but gas piston systems are also extremely reliable and work well.

Which system you choose is primarily a matter of personal preference or the desire to try something new.

AR Pistol Pricing

Under $1,000

For under $1000, it’s more than possible to find a good AR pistol. You’ll have a standard upper, lower, and trigger in this price range, and all of the parts will likely be standard military-spec.

This is a great place to start for most people, and you’ll probably end up buying a brace and optics on your own. Also, the handguard might be nothing fancy, and the pistol grip will likely be something fairly standard. AT this price point you’ll find brands like PSA, Radical Firearms, and Foxtrot Mike.

Over $1,000

For over $1000, you’ll start to see higher-end features as you’re willing to spend more. Some of the first things to get included here will be the pistol brace and an upgraded or free float handguard. From there, the internals will likely be more feature-rich, such as a chrome-lined barrel or more durable bolt carrier group. You can also expect to have things like optics included at the upper end of the price range, though this is uncommon even on higher-end models.

Generally, ARs have gotten a bit more expensive in the past few years, and this is no different for pistols. Depending on your budget, though, you can certainly get into a decent AR pistol for under $1,000. You’ll see brands in this price range like Daniel Defense, CMMG Banshee, Barrett, the Sig Sauer MCX and Maxim Defense.

Shortcomings

While AR pistols offer a lot of upsides, they’re designed to play a specific role in the firearms world. This means that they are better for certain applications than others. 

  • Lack of ranged performance: a pistol being a pistol, you’re certainly not going to get accuracy much beyond 100-yards (or possibly a little more). If you want to reach out to 200, 300 yards or more you’re better off picking up an AR-15 or bolt action rifle to get truly long-ranged performance.
  • Limited calibers: most rifle-caliber cartridges weren’t designed for the short-barreled world of AR pistols, which means they don’t achieve optimal ballistic performance in pistol-length barrels. Some calibers are designed specifically for short-barreled performance (see: the .300 Blackout) but you simply won’t get the same breadth of caliber options with an AR pistol as you will with rifles.
  • ATF Complications: the pistol brace is not without its fair share of controversy. The ATF has signaled to revisit the issue of brace legality, without actually changing policy or position. This inconsistency can make it hard for people to determine if they’re on the wrong side of ATF policies, which makes navigating the world of AR pistols even more complicated than other firearms. Far too many potential AR pistol owners jettison their research before gathering everything they need to make a purchase decision. Also, once you have an AR pistol registered with the ATF, that configuration is semi-permanent. There is no swapping out lowers out once that lower is registered as a pistol. You’ve got a pistol for life.
