TrophyTracker wrote:The SBE, Nova/Supernova, and M1 use the Mobilchoke system, which is different from the tubes that the SBEII and M2 use(Crio). The threads on your gun come right up to the end of the muzzle, where the threads on the Criochokes are about an inch down inside the barrel. The Criochoke will screw into your gun, but there will be a gap between the beginning of the tube(closest to the chamber), and the end of the tapped out channel inside the barrel. This could cause serious damage, since the wad would in a sense, be trying to crawl under the tube on each shot.
This is the tube you are looking for, taken from the Hevi-Shot Catalog
550122 Mid Benelli/Beretta Beretta/Benelli Style Threads, SBE 1, Nova, Super Nova
