ATF Determines AR-15 Pistol With Stabilizing Brace Can Not Be Classified As An SBR

Click to view .pdf
ATF FTB SB15

In a reply to an inquiry made by a Law Enforcement Officer, the ATF’s Firearms Technology Branch determined that an AR-15 style pistol fired from the shoulder when equipped with an accessory such as the SIG Sauer SB15 Pistol Stabilizing Brace would not cause the pistol to be reclassified as an SBR. It has been previously determined through FTB # 99146 that placing a receiver extension of an AR-15 style pistol on the user’s shoulder does not change the classification of the weapon. Additionally, certain accessories such as the SB15 Pistol Stability Brace aren’t classified as shoulder stocks, and as such even improper use doesn’t constitute a design change. The FTB does note, however, that they can’t recommend using a weapon or weapon accessory in a manner not intended by the manufacturer.

Although decisions can be reversed at any time, this response is clearly in line with the SB15 Pistol Stabilizing Brace as being “ATF Approved” prior to its sale.

    Yet another example of modern engineering and innovation rendering a stupid “law” completely null. Can we just remove SBRs and SBSs from the NFA now?

        yes, for all that is good and holy… Someone please get the BATF to catch up with current/contemporary technology.

    Is it an ATF regulation that’s dumb or a law passed by Congress that needs to be updated?

    Please stop talking about this brace. It works well as a brace for disabled people like myself end of story. If they make it illegal that would hurt people who are disabled and need it to shoot. I am loosing the ability to use my left hand, this brace allows people that cannot the ability to shoot AR pistols.

      I understand the reasoning for that, as in anyone who is handicapped/doesn’t have full range of motion/etc.

      I still just don’t see why many other people want it. To me it seeps terribly inefficient for anyone using it in target shooting, hunting, or combat. The first two categories I would want better support and the third there are other weapon systems in that size that would work better.

      If anyone would like to enlighten me as to reasoning/context behind it, please do. Oh and I do understand the “because I can” mentality.

        The main use I can think of for these and AR pistols in general is vehicles. Not many pistols offer the versatility of an AR platform or a 30+ round mag capacity. A carbine length barrel proves unwieldy inside a vehicle and around windows etc. so the solution is either an sbr or one of these. I’d never trust an AR pistol in regular combat use but if i knew I was going to be attacked while driving a vehicle, the most practical solution seems to be a short-barreled AR. But then again sub-16in barrels have become popular with a lot of so-called “elite” units these days, in military and law enforcement, so maybe vehicles aren’t the only practical application.

    the ar pistol platform is great for hunting. if you want put a 50 Beowulf for deer. or 223 /5.56 or if used as an entry gun. as I do in law enforcement put a flaming pig on muzzle and use it to breech. also for people that have limited mobility it can be used in a wheel chair with ease because it is small and lite. the bolt can be pulled easy because it has a handle. just me but if you like guns you should be glad that the ATF allowed the brace to be sold it has its place and its uses.
