I would like to use my .308 suppressor on some of my other guns and was wondering if anyone can help me find a clamp on barrel adapter that will provide threads without actually threading the barrel. Does such a thing even exist? What I am picturing is either a collet or a split collar that provides the 5/8"-24 threads needed for mounting. Two guns in question are a 10/22 standard barrel and the other is a bull barrel that measures 0.810" OD. Ideas?
