I was thinking of getting my barrel threaded for a mb . A friend mentioned that he discovered one you could clamp to barrel so i gave it a shot. Had low expectations but i was really impressed with recoil reduction maybe 30%. Only con is that it is bulky and weight but for an old 308 norma mag could not justify paying a gunsmith . That would be like putting perfume on a pig .Not sure on rules gor pimping products on here so no names easy to findon net
