Hey Joe, You mentioned a band if you go full shroud to the breech. I ordered a barrel band from crosman last week for a mrod. Someone mentioned that the ID's were 7/8 & 3/4 which is what I need. Alejandro at AC said to make sure that center to center on the band will work with a 1/4 riser. Good luck with your builds. I'm only dealing with my 1322. I'd be going nuts with all your projects on your list.
