If a lower has a SB3 pistol brace, are there any issues later attaching a 16" barreled upper ? Say if you owned a Honey Badger, could the owner put a regular upper on it and disassemble the pistol upper to be in compliance.
also you don'y have to disassemble the upper if you have another pistol lower, even if they're not pinned together. Guess they can't prove "conspiracy" like that.
