Well I'm building my first AR pistol.

Nice GD I have had the parts for one for a while, just haven't gotten around to putting it together. What caliber and barrel length are you going with?

11.5 in 5.56

Just scroll down the page to the video. HEY MIKE, You might benefit from this.

That's fast!

My ar pistol build.

I didn't know you could place a pistol brace on a folding mechanism and still be legal.

I've not read anything that says you can't. The sig mpx pistol folds.

This exact thought crossed my mind. I don't guess I've read anything that says you can't do it either but there's something about it that seems like it wouldn't fly. Looks good, though!

Did some research. Since it's a folding arm brace not a stock it's ok. Armalite even sells one in the configuration as an AR pistol.

Glad you researched the issue.

Since "braces" landed on dealer shelves the ATF has waffled on their legality. My favorite gun shop has a huge sign next to their braced pistols stating "DO NOT SHOULDER".

I like the utility of a pistol with folding brace. Seems like its dangerously close to SBR territory, but if its legal...GREAT!

As a side, the ATF has ruled that shouldering a brace does not constitute illegal assemblage of a SBR...


This is in response to your communication dated January 24, 2014, to the Bureau of Alcohol, tobacco, Firearms and Explosives (ATF). Your e-mail was forwarded to the ATF Firearms technology Branch (FTB), Martinsburg, West Virginia, for reply. In your note, you ask about firing an AR-15 type pistol from the shoulder; specifically, if doing so would cause the pistol to be reclassified as a Short Barreled Rifle (SBR).

For the following reasons, we have determined that firing a pistol from the shoulder would not cause the pistol to be reclassified as an SBR:

FTB classifies weapons based on their physical design characteristics. While the usage/functionality of the weapon does influence the intended design, it is not the sole criteria for determining the classification of a weapon. Generally speaking, we do not classify weapons based on how an individual uses a weapon.

FTB has previously determined (see FTB #99146) that the firing of a weapon from a particular position, such as placing the receiver extention of an AR-15 type pistol on the user’s shoulder, does not change the classification of a weapon. Further, certain firearm accessories such as the SIG stability brace have not been classified by the FTB as shoulder stocks and, therefore, using the brace improperly does not constitute a design change. Using an accessory improperly would not change the classification of a weapon under Federal law. However, the FTB cannot recommend using a weapon (or weapon accessory) in a manner not intended by the manufacturer.

We thank you for your inquiry and trust the foregoing has been responsive.
