Alright getting a few questions about my barrel depth gauge. Hope these pictures help. A 90 degree angle will work on any round, oct/rnd, oct. swamped barrel along any point. As long as your are inletting the barrel halfway and as long as you have the side profiles properly marked. :thumbsup:
My advice is do not try to over think it.. just use it :thumbsup:
