I have a 17 Remington that was originally 14". It had a piece of 22 bbl stubbed onto it and pinned, making it a legal 16 1/2" rifle bbl. It's forend has one screw and an attachment bar under it that connects to the two bbl screws. I also have rifle bbls in 223 and 7/30 and 30 Badger, a 38 special necked to 30 cal. Add to that three Encore rifle bbls, there is a lot you can get done with a single shot.
