What really sets the AR-15 platform above basically all other firearms is the fact that you can do just about anything with it.

Long-range precision build? Check. Battle rifle? Basically, a beefed up AR-15. Lightweight carbine? Of course!

Pistol? Yes!

Read on to learn all about the legality, best braces, complete AR-15 pistol builds, and uppers.

Legality

So, what exactly is an AR pistol? If you want the complex legal definition of a pistol Check ATF’s Website.

The short version is: An AR Pistol is an AR-15 that was built from the start to be a pistol – it also has a barrel less than 16 inches in length and does not have a stock.

AR-15 Rifle Vs. Pistol
AR-15 Rifle Vs. Pistol

Generally, an AR-15 Pistol will have a stabilizing brace instead of a stock, but that isn’t required.

Those are the three major federally important points. Double check your state law before embarking on this kind of build, what federally qualifies as a “firearm” or “pistol” might be an “assault pistol” in your state.

Most of the components on an AR pistol are going to be quite similar to a classic AR-15 build. There are a few key differences to note:

  • Stabilizing brace: an AR pistol cannot have a stock, as it would then be classified as an SBR
  • Gas System: pistol length
  • Pistol buffer tube instead of a rifle buffer tube
  • A vertical foregrip is only allowed when the overall length is over 26 inches

We cover it more in-depth in our AR-15 Pistol or AR-15 SBR article.

Shouldering

Lots of pistol braces are designed to be as aesthetically close to a stock as they can be, without changing their legal definition. In fact, most braces can even be shouldered much like a traditional stock can be.

But the act of shouldering it can be a murky question, legally.

ATF Meme Guy

Many manufacturers and people have concluded that it is okay to shoulder a firearm that is affixed to a stabilizing brace. While the ATF forbade this for many years, in 2017 they issued New Guidelines reversing that.

While the ATF might change their minds again someday, for now, you’re in the clear! So, ready to get your new AR pistol?

Disclaimer that this is not legal advice and you should double-check everything, especially since the laws surrounding this always seem to be in flux.  Also the installation instructions are for entertainment only.  Always have a qualified gunsmith work on your firearm.

Best AR-15 Pistols

Nearly all major manufacturers of AR-15s now offer an AR Pistol option making it easy to get a clone of your main rifle in a pistol format. 

Building your own AR-15 and AR Pistol is a lot of fun and a GREAT learning experience, but not all of us have the time or space to make that happen.

2. Springfield Saint AR-15 Pistol

I personally had a chance to shoot this model at a Springfield demo. It shot very comfortably for such a short barrel and was not terribly loud.

Stepping outside of the budget end of rifles we find the BCM Recce 11 KMR-A. Quality parts and craftsmanship meets a sleek design with a classic KMR Alpha rail.

Sig surely contributed to the pistol craze with their SB15 stabilizing brace and the Virtus pistol has only increased the hype.

Truly a top-of-the-line design, the Virtus features ambidextrous controls, two amazing finishes, and a Matchlite Duo trigger.

Lucky for me, I have been able to shoot this pistol and it truly did impress me.

Piston guns run cooler and cleaner than direct impingement guns.  But unless you’re going suppressed or short…they don’t help that much for average folks.

That’s why I was so happy to be able to test out PWS’ Diablo 7″ piston upper.  We’ve already reviewed their 16″ version with great results.

Build Your Own AR-15 Pistol

If buying a complete gun isn’t enough fun for you, then read on for endless building options. Building an AR pistol is not too difficult with the endless internet resources and companies who have made it very consumer friendly.

Just remember, if you’ve built an AR-15 before – this is basically the same process, just with some different parts. If you want a refresher or if this is your first build, make sure to read our AR-15 Definitive Resource.

There are three major things you need to consider for a pistol build: caliber, barrel length, and brace.

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?

Rifle Caliber Smallest to Largest
Rifle Caliber Smallest to Largest.

Your main caliber choices are going to be 5.56, .300 AAC Blackout, or 9mm. But if you really wanted to go wild, 6.8 SPC and 7.62×39 are also options. We’re going to focus on the big three here.

  • 5.56: this is a great go to if you’re not exactly sure or are wanting this to be a multi-use gun. Ammo is not too expensive and finding the parts for 5.56 is easy.
  • .300 Blackout: looking for a super short barrel or wanting to suppress it? This is going to be your go-to option. .300 Blk is a larger round that was meant to be shot suppressed and can be run through a shorter barrel than 5.56. Learn all about .300 Blackout!
  • 9mm: if you own a Glock and want to be able to swap mags, this might be your option. It’s not as loud as rifle calibers and cheaper to shoot, but parts can be harder to find.

Barrel Length

Ask an AR nut the shortest barrel length 5.56 needs to burn or what length .300 is optimized at and you are sure to get into a heated argument. Here are a few of the most common barrel lengths explained.

Faxon Barrel Assortment
Faxon Barrel Assortment
  • 11.5”: this is a pretty safe bet for 5.56 because it can nearly fully burn and barrels are common. A 10” or 11” rail pairs perfectly.
  • 10.3” or 10.5”: Common among USSOCOM rifles, the 10.3 and 10.5 has been pushing its way into the civilian market as well. I personally have a 10.5” in 5.56 and love it. Yes, there are some fireballs and it is quite loud, but it is a comfortable length for me and allows for a lightweight build.
  • 9”: in .300 AAC, you will get the highest velocity making this the ideal combination. You truly get the pistol feel with this short of a barrel.
  • 5.5”: probably the most common length for 9mm, not really offered for much else, however – the Sig Sauer Rattler uses a 5.5″ barrel in .300 Blackout.

The barrel is a crucial component. If you’re going to splurge on one thing, I would choose a nice quality barrel.

Prices vary immensely and you often have options when it comes to finish and material. Here are a few manufacturers and their 10.5” pricing for general comparison.

Generally, when you’re looking at pistol length barrels one thing that isn’t on your mind is long-range precision since the length of the barrel prevents the round from really stretching its legs.

However, that doesn’t mean your barrel can’t help it as much as possible. If you’re looking to get that little bit more out of your 5.56 – using a .223 Wylde barrel might be the answer.

Rainier Arms is not only one of the few makers of a pistol length barrel in .223 Wylde, they also make some of my favorite AR-15 barrels period.

Brace Yourself

The key defining component of the AR pistol is the brace of course.

HK, CZ, Sig, AK, and even Mossberg 590 and Kriss Vector Braces are designed by SB. My pick is their SOB model. It is the skeletonized model of their original design and comes in black and FDE.

If you want it to look like a stock from the side, this is a great option.

While the Shockwave is not as comfortable to shoot with because it is marketed as a “blade” it is a less-expensive and simpler alternative. 

Maxim Defense CQB Pistol BDW Brace

Hands down one of the best pistol braces on the market, but also with a price tag to match. This is the Rolls-Royce of pistol braces. Solid, easy to use, and looks outstanding.

The only problem is that at this price, you don’t want to put this on a budget build or a truck gun. This is for serious use only. If you plan on using your AR pistol as your home defense gun, you might want to shell out the cash for this.

KAK Shockwave Buffer Tube

The un-sexy part of any brace or stock, the buffer tube. Don’t underestimate this component though – it’s important.

AR-15 Pistol Optics

Over the past year, optics have most certainly become my favorite accessory and favorite thing to research.

They’re incredibly important and can make or break a firearm. On an AR pistol, the main considerations are size and zoom.

You need to think about how far you’re going to be shooting and what conditions.

Accessories & Upgrades

Anything that you can put on a normal AR-15 rifle, you can put on your AR Pistol. From slings to a new High-Tech BCG, it’s all the same.

Our first stop would be a weapon mounted flashlight like the SureFire M600 Scout.

Once you have that mounted, you’ll need a sling. Just because it is a pistol, doesn’t mean there are holsters for it. A sling is a must-have for any firearm the size and weight of an AR pistol.

Personally, I like a 1-point sling for an AR pistol – like the Magpul MS4.

The Pros and Cons

Over the past few years, AR pistols have been increasing in popularity for good reason. The ATF has yet to be crystal clear on their stance but we can’t expect too much.

If waiting ten months and paying an extra $200 isn’t a viable option, the AR pistol might be for you. The platform is extremely versatile and has quickly become one of my favorites as the building ideas just seem so endless.

Lone Blue AR-Pistol
Lone Blue AR-Pistol

Because it is so technically similar to an AR15, you have the same pool of options when it comes to accessories.

The ATF has proven itself to be a bit of an unpredictable bureau. It can surely be unsettling to invest $1000 into something that might become illegal but you do have other options.

If you are looking to be a stamp collector eventually, you can always file a Form 1 and have fun with your AR pistol while you wait for the SBR stamp.

Need more options? Remember that the AR-15 is basically the most customizable firearm platform ever made. Browse through our AR-15 Definitive Resource and find anything you need.

    Just built a PSA 10.5 in 5.56 for my first ever build. Love it. Thinking of going shorter. Maybe in a different caliber. 9 mm or .40 S&W. Should I build one from scratch or modify my existing one with a new upper? Any thoughts would be appreciated

    • James K Brockman

      In a barrel of 7-8" Your might want to consider PC 10mm. The extra barrel length makes a 100 into a bear killer should you want to hike or pack it in near country or use in a camp. It would be perfect for home defense, truck gun, it not going to be an over penetrating round either. There are options to make it a piston power instead of infringement gas which would eliminate the buffer tube out the back as well making it even more compact and lower can be dedicated to your choice of mag to make a side or compact carry gun.

      Switching to a pistol caliber is a bit harder for the lower, you can get a Stern Defense magazine adaptor and they work awesome - but then you're stuck taking that in and out each time you want to switch. I have a dedicated lower that I just keep a Stern Defense adaptor in but I'm looking to replace it with a dedicated purpose-built lower soon. PSA has some great pistol kits, pistol uppers, and pistol lowers. I use one of their complete uppers in 9mm and it has been outstanding! We have a complete review on the PSA PX-9 also!

    What's ATF's rationale behind prohibiting vertical foregrips on pistols?

    3 months ago
    • Adam

      It has to do with the definition that pistols are supposed to be shot with a single hand. Now arguably you can use your off hand as well but there should only be one place to grip the gun. Its dumb and it doesn't make sense but that is the reasoning.

    So I bought the Springfield Saint pistol and shot happily for months, until my NFA was approved and I picked up my SilencerCo Chimera-300. I put ASR mount muzzle brakes on my .308, 6.5 Creedmoor, AR-15 rifles ... and then realized that the threads on the Saint Pistol are under the hand guard, and the diameter doesn't support any suppressor. Contacted Springfield for advice and got an immediate "Tough luck!" I've ordered a shorter hand-guard from Midwest Industries ... and will do my first barrel-nut replacement when it arrives. Wish me luck. That kind of work is more than I usually do in my limited gunsmithing history. Suggestion to Springfield ... don't cover the barrel threads on the next version of your Saint Pistol.

    One thing to note in your definition section; there’s actually no requirement that an AR pistol barrel be under 16”. As long as it’s originally built as a pistol, until you put a stock on it, it remains a pistol regardless of upper. So one could have an 18” barrel pistol as long as it was originally built into pistol form. Would be pointless to do so, but just wanted to point out that the federal definition of pistol only requires that “it be designed not to be fired from the shoulder”. This comes from a detailed analysis of many ATF opinion letters on ARFcom.

    It is my understanding if a lower receiver is registered as a rifle or a pistol is cannot be converted to the other weapon or visa versa. Am I correct? Otherwise people could circumvent handgun laws by turning rifles into pistols.

    1 year ago
    • David

      A pistol can become a rifle, a rifle is forever a rifle. If you build an AR Pistol, you can always change the barrel for a 16"+ barrel and throw on a real stock and have a "rifle" and still be able to convert that "rifle" back into a "pistol". However, if the lower was built out as a rifle to start with - it will always be a rifle, no matter what. The only way to get a sub 16" barrel on a rifle is to get an SBR stamp.

    Great article. Can't say enough about all the options for building an AR pistol. My first AR build was a 7.5" PSA upper, enhanced trigger, Aero lower, light, sling, Vortex Sparc red dot and 3 20rd PMags ... all for under $800. Not bad for a home defense/truck gun. Yeah, it barks a little when you shoot it, but it's never had a malfunction and is very accurate out to 50 yards.

    AR pistols are awesome. No need at all for an SBR. Pistols can be concealed and carried loaded in a vehicle. All good. 9mm is good to 100 yd, that is enough for me. For bigger punch, x39 is way cheaper than 300 blk and has the same ballistics.

    1 year ago
    • Green

      You might want to revisit that thought. 300 blackout has slightly better ballistics, accuracy and distance. The whole point of the 300 was to combine the range of the 5.56 and the impact of the x39.
