Armaspec SRS Buffer Kit Gen 4 Features The Armaspec SRS Buffer Kit Gen 4 is built around the Stealth Recoil Spring a self contained multi stage drop in replacement for a standard AR-15 buffer and spring. The SRS Gen 4 design keeps the buffer spring from rubbing against the inner wall of the buffer tube which produces smoother quieter cycling compared to a standard setup. A second stage within the spring system helps reduce felt recoil significantly giving the shooter a more controlled comfortable experience shot after shot. The H2 buffer weight used in this kit is rated at 4.7 ounces letting shooters tune the system s cycling characteristics to their specific rifle and ammunition. Beyond the recoil spring itself the kit includes a mil spec 7075-T6 six position buffer tube along with a steel castle nut and end plate providing every part needed to mount a stock assembly onto a lower receiver. This complete approach means builders are not left sourcing individual components separately or guessing at compatibility. Fitting standard AR-15 Gen4 platforms the kit installs as a straightforward upgrade during a build or as a replacement for an underperforming factory buffer system. For shooters focused on smoother operation and reduced felt recoil the Armaspec SRS Buffer Kit Gen 4 delivers a complete engineered solution in a single package.
