Tandemkross “Bolt Keeper” Extended Bolt Stop for Ruger Mark IV 22/45 – Black

Tired of the difficulty of manipulating the stock bolt stop lever? The TandemKross “Bolt Keeper” Extended Bolt Stop for Ruger® Mark IV™ 22/45™ facilitates effortless locking and releasing the bolt by providing an extended, wider, lever.
