There is a company that makes stick on aluminium ribs. I see them on trap guns as guys try to follow the trend of super high ribs. As I remember you can remove these by pulling fishing line through the tape joint. No perment damage to the gun! I tried to buy steel rib material to replace a rusted rib and found no one has any to sell, Simmons had a little but would not sell it. I ended up making my own?
