In a letter to short-barreled shotgun manufacturer feds say shouldering an SB15 could be illegal.
In a letter reportedly written to a small home defense shotgun maker, the nation’s top gun control regulator says shouldering a Sig Sauer-made SB15 pistol stabilizing brace could change a firearm’s classification rendering it subject to bureaucratic and expensive National Firearms Act rules.
The Nov. 14 letter was written in response to Black Aces Tactical owner Eric Lemoine’s submission of a short-barreled shotgun design that incorporated the SB15 brace. The brace is intended to allow a shooter to fire an AR-style pistol with one hand using a Velcro strap to attach it to the arm.
The ATF letter has many AR pistol owners concerned as it could be seen as a blanket determination on illegal use of a Sig Brace, subjecting violators to years in prison and a permanent ban on firearms ownership.
“The submitted weapon, as described and depicted above … is not a ‘firearm’ as defined by the NFA provided the SicTac SB15 pistol stabilizing brace is used as originally designed and not used as a shoulder stock,” wrote Acting Chief of the BATF’s Firearms Technology Branch Max Kingery. “However, should an individual utilize the SigTac SB15 pistol stabilizing brace on the submitted sample as a shoulder stock to fire the weapon from the shoulder, this firearm would then be classified as a ‘short-barreled shotgun.’ ”
