I hope I did not miss the obvious but I have been unable to find a discussion about barrel threading for brake mounted QD of suppressors. I will be purchasing, and waiting, for a suppressor (probably a TBAC 30BA for use with a .223 and a .308) within the week (waiting on trust) and have two rifles, one with a factor flash hinderer and the other bare. So, who have you had do barrel threading to meet the concentricity and alignment expectations of the suppressor manufactures? I'm in Michigan and we have plenty of gunsmiths that offer brake threading/timing services for $100-$150, but I'd like it to go well. How did you pick the gunsmith you worked with? Have you had to have factory threads reconditioned? Did it go as planned? Your experience and advice is welcome. Thanks in advance!
