I can’t seem to find a ss thread protector that is 1” OD. I just bought a GAP PPR and I don’t really want a brake and a suppresser is not legal in my state. I thought it came with a thread protector, but it just had a rubber tube over the threads. I’m in my 10 day waiting period. I did not dig through the box that hard, but I would guess that it would be on the barrel. The barrel finishes at 1” and I would like something that looked good. The closest I’ve found is an .92 OD and it was black. I’m also considering a chode brake, so it’s not soo bad at the range, but reviews are hard to come by. I have custom ear plugs and don’t really want to wear muffs over the top.
