X-RING® Maintenance Kit

The X-RING Maintenance kit includes everything you need to re-tune your X-RING bolt and recoil system. The included items are suitable for both current and previous bolt design generations. If your bolt features an engraved “Z” on the lower left-hand side, utilize the longer, 1/2” inch Firing Pin Stop Pin. If your bolt lacks the engraved “Z”, opt for the 3/8” inch Firing Pin Stop Pin.
