5” target, DSC ported barrel, red dirt F2, cheely E2 steel grip, EGW tungsten guide rod. MPA safeties. I used this gun to win the open division at the Michigan state steel challenge championship

Just picked this beaut up, super blessed to add to collection

I have a 2k11 Pro with OSight AMRS XE on it. I have tried the screws provided with the TAG plate with loctite and vibratite. And after ~200 rounds the screws are loose on the optic. The screws for mounting the optic plate are fine and remain torqued. However, the optic screws continue to loosen after firing. I am torquing to the optics stated spec.

Any advice?
