I'm making the assumption (yep, know what it means) that the Crio are the first version that came out with the first super sports. The ones with the threads at the end of the barrel, not about an inch down, which I believe are the Crio Plus. If I'm correct on that, then the same 5 constrictions apply - cyl, Imp, Mod, Imp Mod, and full. Have both kinds in Benelli's I own: Crio in 12ga. Super Sport and Crio Plus in the 12ga. Cordoba and 20ga SS.
