I own several barrels for my Renegades and I would really like to have a separate stock for each of the barrels. But what I did is designate one stock for all the switching, and it seems to work for me.
Also if I knew how easy it was to switch barrels on the Renegades and make them do anything an inline can do, I doubt if I would have ever purchased most of my inlines. I could not part with my Whites, but the rest of them I could let go easy.
