I have a 20G A10 with 32 inch barrels. I have a set of 30 inch 28g barrels as well. The 32 inch 20G barrels seem perfect for that gun. Its my go to pheasant gun. My gun did need "adjustments" as well. Only one of the barrels wouldn't fire when I got it. Great service on the repair though. They paid shipping and where very fast.
