**New BATF Ruling You Can Shoulder This Arm Brace Like A Stock !!

Only The SB Brace Can Be Shouldered According To The Letter By The BATF.

In a letter dated March 21, 2017, ATF reexamines its earlier position, which stated that shouldering a PSB-equipped firearm could constitute the making of an unregistered short-barreled rifle under the National Firearms Act (NFA).

ATF now states:

“With respect to stabilizing braces, ATF has concluded that attaching the brace to a handgun as a forearm brace does not ‘make’ a short-barreled firearm because … it is not intended to be and cannot comfortably be fired from the shoulder.” The letter continues: “Therefore, an NFA firearm has not necessarily been made when the device is not re-configured for use as a shoulder stock — even if the attached firearm happens to be fired from the shoulder.”

The following passage from the letter acknowledges the confusion surrounding the January 2015 “Open Letter on the Redesign of ‘Stabilizing Braces’”, Clarifies that ATF does not consider shouldering a PSB-equipped firearm, in and of itself, to render it an SBR.
