I'm waiting on a suppressor for 22 rimfire. The dealer said the ATF is taking about 6 months to process paperwork, so I've got some time. I've got a bull barrel Ruger MK2 as well as a Romanian trainer that I want to have threaded. Anyone know of a reputable shop in Michigan that would like to do this work? I was thinking of keeping it in state because of shipping firearms, but maybe it would be better to send them off to have the work done if no one in MI can do it. Any members here have experience threading barrels?
