Does anyone know if the SBE II barrels can be cut down and re-threaded for the Crio-Plus choke tubes? I have a LH Max 4 and the only length it comes in is 28" and I would prefer a shorter barrel, if possible. If this barrel cannot be re-threaded for the Crio-Plus chokes, could it be re-threaded for standard Beretta tubes? I have a Beretta O/U that would be nice be able to use one set of chokes for 2 guns. Thanks for the help!!
