Product picture is incorrect. You will be getting the 3 base set screw rings instead of the 4 base set screws as shown. Works great on compact scopes but not what I was looking for on my full size scope.
Pros: Decent quality.. built in scope stop
Cons: This is NOT the 120mm mount.. this mount is 100mm with only 3 base set screws.
