Tactical Solutions Shock Buffer Features The Tactical Solutions Shock Buffer directly replaces the factory bolt stop pin on a Ruger 10/22 addressing a well-known long-term wear point on this popular rimfire rifle. Every time the bolt cycles rearward it strikes the bolt stop pin and over tens of thousands of rounds that repeated metal-to-metal contact can lead to receiver cracking around the pin hole. The polyurethane buffer absorbs that impact instead cushioning the bolt s rearward motion and removing the source of that long-term stress on the aluminum receiver. This makes the buffer a preventative upgrade well worth installing before wear becomes a problem rather than after. Beyond protecting the receiver the polyurethane buffer also reduces felt recoil and quiets the rifle s cycling noise since a polymer-to-polymer or polymer-to-metal impact is inherently quieter than metal striking metal. This buffer is designed specifically to fit the .22 LR Ruger 10/22 and installation is a simple swap for the factory bolt stop pin with no permanent modification to the rifle. Tactical Solutions notes the buffer may ship in various colors but once properly installed it will not be visible on the finished rifle. For any 10/22 owner planning to put significant round counts through their rifle this is a low-cost high-value upgrade for long-term reliability.
