Oh heck..I have one of the Benelli Sports...I really don't like the darn thing. It has a rib you can take off and change to another. Shoots ok but I'm going to get rid of it. Not my cup of tea. Don't think I've put 2 boxes of shells through it. Nice gun but I have a bunch of them. And that criogenic thing is a bunch of malarkey...in a shot gun. A rifle...that may be different. Pressures are much different in a rifle. JMHO
