Armaspec SRS Buffer Kit C Gen 4 – AR-15/AR-10 Sound Reduction System

The Armaspec SRS Buffer Kit C Gen 4 replaces your standard carbine buffer system with a spring-free design that reduces felt recoil and eliminates buffer spring noise. Built around captured tungsten weights and polymer dampers, this kit delivers smoother cycling and quieter operation without compromising reliability. The Gen 4 version refines the original SRS design with improved durability and consistent performance across a wide range of ammunition types.

This kit is compatible with mil-spec carbine receiver extensions and installs without permanent modifications. The captured design prevents spring twang and buffer tilt, while the tuned weight configuration provides reliable cycling with standard 5.56 NATO and .223 Remington loads. Installation requires only basic disassembly of your bolt carrier group and removal of the existing buffer and spring—no gunsmithing or special tools needed.
