The Colt AR15A4 Bolt Ring, 3 Pack is a simple but critical small part that keeps your AR-15, AR-15/M4, or M16 bolt running smoothly. Each ring is built to Colt factory specifications for a precise fit on the bolt tail, helping maintain proper gas seal and consistent cycling in compatible AR-15 rifles such as Accurized HBAR, Government Carbine, and Match Target variants.

This three-pack is ideal to keep on hand for routine maintenance, troubleshooting short-stroking issues, or refreshing a high-round-count rifle before a training class or range session. Easy to install and replace, these rings support reliable function so you can focus on shooting rather than chasing malfunctions, all backed by Colt’s long-standing reputation for quality AR-15 components.
