Armaspec SRS Buffer Kit H2 Gen 4 – AR-15 Sound Reduction System

The Armaspec SRS (Stealth Recoil Spring) H2 Gen 4 buffer kit reduces bolt carrier noise and felt recoil in AR-15 platform rifles. The captured spring design eliminates the metallic ping of standard buffer systems while providing H2-weight buffering for mid-length and carbine gas systems running heavier bolt carriers or suppressors.

This Gen 4 system features a tungsten-weighted buffer body with an internal multi-spring design that's fully captured—no need to remove the buffer retaining pin during installation. The kit includes the SRS buffer assembly and proprietary recoil spring. Compatible with mil-spec AR-15 carbine receiver extensions. Drop-in installation requires no gunsmithing or permanent modification.
