Hey all, I have an AK that I just removed the barrel nut from, only to find that there are no threads. I can't remember the exact diameter, but it is too small to be threaded to 14mm. It can however be threaded to 12, and I was wondering where in the Indy area I could get it threaded, and what kind of 12mm flash hiders/ muzzle brakes you would suggest. I like the 74 style, but would it have to be drilled out to accommodate the larger bullet?
