So I was wondering if there was a "minimal" length from the end of the muzzle to the end of the break? I'm thinking on "setting back" the MB and wondering if that would affect the performance? or accuracy? So normally the MB would thread on with about .700 worth of thread, setting back an additional .400, moves the barrel muzzle closer to the end of the MB and I'm still able to clear the ports. Let me know what you think?
