I think a 24" rifle sighted Imp Cylinder barrel was available for a time. I have my eye out for one. I love my BPS, I use it for all waterfowl and turkeys. It has a 30" barrel and I shoot a modified steel approved choke for the steel shot and a full for the lead for turkeys. I keep my 20" Cylinder 10 ga. SxS AyA Matador double loaded with slugs usually (sometimes #4buck) hidden but accessable in the TV room for those home invasion scenarios.
