Up for sale I have a New in wrap Armalite AR10 factory muzzle brake. This is the brake that comes on Armalite's ban legal AR10. The brake must be pinned and welded to the muzzle to be legal on a ban compliant rifle as the brake has threads. Armalite has them for $30.00 plus shipping. I'll take $23.00 shipped. Please post I'll take it and sent me a email if you want her.
