Went to check into getting a barrel threaded on a bolt action rifle for a muzzle brake. I was told that the machinist would remove the barrel from the action to thread the barrel. I asked to talk to the machinist the gun shop used but shop wouldn't supply that info.I think they are afraid I would try to bypass them. That to me doesn't show a great relationship between the gun shop and machinist. I asked how he would properly index the brake with it off the action. No clear answer. Seems that removing the barrel could possibly effect the position of the recoil lug affecting my bedding job and also possibly affect the headspace of the rifle. My biggest concern is not being offered the ability to talk to the machinist to address my concerns. I don't want a guy with a $300 Harbor Freight lathe messing up my gun. Anybody in the Vancouver/Portland area have a gunsmith they can recommend?
