Product Description The TANDEMKROSS "Shock Block" Bolt Buffer is a must-have upgrade for any Ruger PC Carbine or Ruger PC Charger owner. Engineered to eliminate the destructive metal-to-metal contact between the bolt and the receiver pin, this drop-in buffer features a high-durometer elastomer insert that more gradually absorbs the impact force of the reciprocating bolt assembly. The result is reduced impact stress on the receiver, minimized vibration, and extended firearm lifespan. Constructed with an aluminum-reinforced body, the Shock Block is built to exacting tolerances for high impact resistance and superior load-bearing properties. Installation is completely tool-free, making this one of the easiest and most effective performance upgrades available for the Ruger PC platform.
