So I asked a gunsmith about if my axis sporter in 30-06 could be threaded for a suppressor and he said no, because the diameter is too small. So I measured the muzzle myself and it's around .58". So yes that'd be too small to cut 5/8x24 threads but I was thinking, what about 9/16x24 or 14x1L? Both of those threads are used on 308 rifles like the FAL and 308 AKs, is there any reason I couldn't have my axis threaded in one of those sizes instead?
