The TandemKross Shock Block Bolt Buffer (TandemKross part no. 0118N0039BLK1) is a drop-in polymer insert built to cushion the bolt-to-receiver-pin contact inside a Ruger 10/22. Every cycle of a 10/22’s bolt slams metal against metal at the rear of the receiver, and over time that impact wears the receiver and adds vibration and noise to every shot. TandemKross’s high-impact-resistant polymer buffer replaces that contact with a cushion, smoothing out the action and cutting down on wear.
