Very pretty gun!
I have a 20/28 A-10 set with Rose&Scroll built on the small A-10 frame.
CSMC will also build you 20 or 28 on the 12 gauge frame.
Best small gauge o/u available today in my opinion!
I have a few boxes on doves and Sporting Clays with mine and no problems.
It has become my favorite field gun for upland birds.-Dick
