Works will for me! paired this with the viridian mylex 1-8x scope. - Viridian OPMOD V2 30mm 1-Piece Scope Mount

This mount worked well for me to mount up a Viridian Mylex 1-8x scope. When bolts are torqued correctly, this scope holds zero no prob. Even when I swap uppers and lowers. No problem. Always at zero after sighting it in the first time. Make certain to torque the pic rail bolts to 65-in/lb. I have two of these in operation on two separate AR rifles and I have no complaints what so ever for the price I paid. Bargain!
