Dirty Bird AR-15 4.6oz H2 Buffer
The Dirty Bird AR-15 4.6oz H2 Buffer is a reliable upgrade or spare for builds that need a little more buffer mass for improved function. H2 buffers are commonly used to help smooth cycling, reduce bolt speed, and soften recoil impulse, especially on hard-use rifles and setups tuned close to mil-spec performance.
Built with a machined aluminum body and a rubber bumper, this 3.25″ carbine buffer is compatible with mil-spec and commercial AR-15 receiver extensions and is proudly made in the USA.
