Just wondering if anyone has cut down and re-threaded their original 16" barrel? Due to Michigan law I had to have my original PWS muzzle brake pinned and welded. I need to change out the existing muzzle brake to accommodate my a new muzzle brake for my future suppressor. In the past I know removing a pinned and welded muzzle brake always messes up the existing threads, so I know they will have to cut and re-thread the barrel. I'm curious because they would have remove that little "bump" at the end of the barrel where the muzzle brake seats. Just wondering if anyone else has done something similar? Thanks.
