I just took the barrel off my 15-22 and I have a co-worker with a machine shop that is going to put 1/2"-28 threads on the end so I can install a DPMS flash hider I have ordered from Midway. My question is, how much of the end of the barrel do I want to have threaded? I looked over the forum threads and that is one bit of info I didn't see. I did see talk about having the muzzle recrowned after threading though, is this necessary?
Thanks.....................
