Though the ATF’s clarification letter stating that it’s acceptable to shoulder an unmodified arm brace was sent to the law firm of SB Tactical, originators of the Pistol Stabilizing Brace, manufacturers of competing products are declaring it a win for them, too. The argument is that the letter speaks in generalities, rather than referencing a specific brand or model, and states that the market’s interpretation of their January 2015 Open Letter — which definitely applied to all pistol brace manufacturers and was taken to imply that shouldering a braced pistol was a felony — was incorrect . . .
That particular passage states:
To the extent the January 2015 Open Letter implied or has been construed to hold that incidental, sporadic, or situational “use” of an arm-brace (in its original approved configuration) equipped firearm from a firing position at or near the shoulder was sufficient to constitute “redesign,” such interpretations are incorrect and not consistent with ATF’s interpretation of the statute or the manner in which it has historically been enforced.
Whether you believe this clarification letter applies only to SB Tactical or to all arm braces that have received ATF FTB approval, the champagne has certainly been popped all around.
Over at the Gear Head Works booth at NRAAM 2017, they were showing off their Tailhook MOD 1 and MOD 2 braces on all manner of pistol configurations, from ARs to CZ Scorpions to MP5s to, you guessed it, GLOCKs…
