Unfortunately, ”pistol stabilizing brace” was exploiting a loophole to avoid laws regarding short barreled rifles. Wasn’t an invention of progressive snowflakes.
That’s OK ... I put a cloth mask on my pistols. :)
Umm. No.
Braces have been around for quite some time.
Modern AR braces, about 12 years now.
Every single tech opinion clearly stated/states that when used as reviewed, incidental use on the arm, chest thigh or gasp, even shoulder, does make the system a SBR.
The critical piece used to be whether or not the accessory was designed or intended for use from the shoulder. The exploitation as you label it. As if that would make it darker and more evil... Irrational minds at work. Congress asleep at the wheel.
Now, the proposed criteria is much less objective than before.
The goal of ATF is to make everything unacceptable.
