Mil-Spec Enhanced Carbine Buffer Kit AR-15 6-Position

Mil-Spec Enhanced Carbine Buffer Kit The Mil-Spec Enhanced Carbine Buffer Kit is engineered for serious shooters looking to upgrade their AR-15's recoil system with superior materials and performance components. At its core is a 6-position receiver extension made from 7075-T6 aircraft-grade aluminum, delivering nearly twice the strength of standard 6061 alternatives. Paired with a Dirty Bird 17-7 stainless steel carbine buffer spring, this kit provides exceptional fatigue resistance, corrosion protection, and long-term reliability. The included H1 buffer (4 oz) uses two steel and one tungsten counterweight to tame recoil without over-dampening, making it ideal for most carbine-length gas systems. Finished off with a hardened castle nut featuring staking cuts and a Mil-Spec end plate, this American-made kit ensures consistent, rugged performance on any build.
