TANDEMKROSS Shock Block Bolt Buffer Features The TandemKross Shock Block Bolt Buffer eliminates the metal-to-metal contact between the bolt and the receiver pin that normally causes bolt-battering of the receiver on a Ruger 10/22 over thousands of cycles. By absorbing that impact the buffer reduces stress on the receiver itself helping protect the rifle s structural integrity over a long service life. It also eliminates the vibration caused by that same metal-to-metal contact resulting in a noticeably quieter and smoother cycling action. Made for high tolerances the buffer offers high impact resistance and superior load bearing properties suited to repeated use. Installation requires no tools at all making the Shock Block a true drop-in upgrade that any 10/22 owner can complete in minutes. The material used is oil and solvent resistant ensuring the buffer continues to perform properly even after repeated cleaning and lubrication of the action. This inexpensive addition is a practical first upgrade for any 10/22 owner looking to extend the life of their rifle s receiver.
