The Colt Carbine H2 Heavy Buffer is engineered to deliver smooth, consistent cycling in AR-15 and M16 carbines that use standard carbine buffer tubes. Built with an aluminum body and internal tungsten and steel weights, this buffer adds carefully tuned mass to help control the action and enhance reliability in rifles with shorter gas systems.

This H2 configuration weighs 4.6 oz, providing increased dwell time that helps reduce bolt bounce and soften felt recoil, especially in fast-running carbines. Ideal for range use, training, and refining the shooting characteristics of your AR platform, it offers a simple drop-in upgrade that works with standard AR-15/M16 carbine buffer springs. Backed by Colt’s long-standing reputation for dependable performance, the Carbine H2 Heavy Buffer is a practical enhancement for shooters seeking smoother operation.
