For SUBS I can use my SilencerCo Osprey45... for SUPERS I will run my .30 rifle can, made by a friend/student of mine... from Ozark Armory... It will wear the Osprey if I stock it with SUBS, The only issue... I am about to buy an AR in 308. I wanted the RRA LAr-8 Elite Operator, however, I may go with the CMMG complete rifle from CDNN (16")... that should be my home defense gun, so it will have to wear the rifle can... running 168 gr AMAX TAP... I am still on the fence a bit between the RRA and CMMG. I like that the CMMG uses "standard" parts, unlike the RRA that uses a lot or their own part, specific to the LAR-8. Justin
