Why not get a quick change brake/adapter for the can and put one on each barrel. I use Silencerco asr

Some barrels don't have enough meat on the muzzle for11/16 or 3/4 and 5/8 can be thin between threads and bore. Muzzle belling as another has stated can be an issue and not a fun 1! I wanted to do a barrel change on an 1895 for that reason.
