Tru-Glo Gobble Stopper, various low power scopes, and am now using a Sig Romeo red dot. They all have withstood the recoil of turkey loads. I've actually been pretty impressed with the Gobble Stopper, as I used it for years on a 3 1/2 inch Benelli. I also have one of the Tru-Glo open dot sights that is no longer made. It didn't like the 3 1/2 loads, but worked well on everything else.
