Dirty Bird AR-15 True Mil-Spec Carbine Receiver Extension / Buffer Kit – H3
The Dirty Bird AR-15 True Mil-Spec Carbine Receiver Extension / Buffer Kit is built around quality components without the shortcuts found in many lower-cost buffer systems. The six-position receiver extension is machined from American-made 7075-T6 aluminum for increased strength, while the 5.5 oz H3 buffer uses individual tungsten and steel counterweights to support proper cycling and help reduce bolt bounce.
A chrome silicon carbine buffer spring, hardened castle nut with staking cuts, and mil-spec end plate complete the system. Designed for dependable service in compatible AR-15 carbine configurations, the kit is made in the USA and backed by Dirty Bird Industries’ Limited Lifetime Warranty.
