[QUOTE="J E Custom, post: 1702386, member: 2736"] I truly don't understand the use of threads with that little amount of barrel tenon. If you thread a 308 bore with a 7/16 thread diameter you will end up with a barrel wall thickness of between .045 thousandths and .050 thousandths at the minor diameter. and with the tops of the threads having a little flat (Like they are supposed to) you will end up with 80 to 85% thread engagement Max. 1/16 of an inch is .0625, so the barrel wall would be less than 1/16th thick. and if it were dropped, the barrel tenon could be bent or worse broken off. They are relying on the muzzle brake for strength and in my opinion that is not a good idea because it rely's on to many factors that can cause catastrophic failures. I can only recommend the way to do things and hope that it saves someone from from a failure or worse. J E CUSTOM [/QUOTE]
