humm I had a Gracoil on one of my guns. Don't remember it looking like that. Might be a earlier one. Sometimes stock has to be inlet to fit ,depends on the gun. I had one on a browning XS special But like I said it was much different. They work ok, but they should be set to break just at the highest point of recoil. Set too light, I found stock movement against the cheek was terrible. I don't have one on my current gun, recoil is not a big problem for me. good luck with it
