So I’ve been building Ar pistols and selling them which is way too much fun. Here is my latest; called the flying squirrel. Psychiatrist says I have The AR 15 building disorder. Only one I have is the top or fist and the CZ75 Omega w/ green grips. oh, my personal pistol at top has the BFS III I’m it 10.5” .300blk I’m dying to blast off!
