ATF Response on Firing AR-15 Pistols from the Shoulder with SIG Sauer Pistol Brace

The SIG Sauer SB15 Pistol Stabilizing Brace has become a popular accessory for AR-15 pistols in the past year. The removable buffer tube attachment was originally developed for a disabled veteran to improve the ergonomics of the AR-15 platform.

Since the introduction of the pistol brace, many folks have questioned the legality and advisability of shouldering an AR-15 pistol with the brace attached. A recent letter from the Firearms Technology Branch of the ATF dated Mar. 5, 2014, may answer some of the questions floating around the firearms community.

The letter (below) addresses specific reasons why "[the ATF] have determined that firing a pistol from the shoulder would not cause the pistol to be reclassified as an SBR".

G&A wants to know from our readers: Does this letter give you the confidence to legally shoulder an AR-15 pistol?


G&A always emphasizes safe handling of firearms and advises that users follow federal, state and local laws and all manufacturer directions when using the pistol brace.
