You need to purchase scope rings to install a scope onto your scope mount. Some scopes already come with their own scope rings but you can get this set of high scope rings to position your scope higher (often needed when you have a high front sight that might get in the way - such as on an M16 rifle). Full metal construction with thumb-screws for securing onto scope rail. Philips screws for securing scope.
Did you know that scope rings are not used solely for installing scopes? Scope rings are also used to secure lasers and flashlights onto RIS rails.
