I received my Accura from Cabelas today and I had ordered a set of Durasight Z-2 Alloy 2pc base and medium rings. Has anyone else used these on a muzzleloader? They seem like they might be easily knocked off by recoil. I put a set of TC Gorilla Mounts on my Kodiak and they, for the price, are stronger looking to me. Does anybody know who might sell the Gorilla Mounts?
