Armaspec SRS-9 Stealth Recoil Spring 9mm Luger Silver AR-15 Gen 4

The Armaspec SRS-9 Stealth Recoil Spring is a self-contained, multi-stage drop-in replacement for the standard buffer and recoil spring on 9mm Luger AR-15 platforms. Part of Armaspec's Gen 4 lineup, the SRS-9 consolidates the traditional buffer and spring weight stack into a single integrated unit designed to smooth the operating cycle, reduce felt recoil, and tame bolt bounce on direct-blowback pistol-caliber carbines.

Built around a 6.4 oz assembly with a silver finish, the SRS-9 installs in place of a standard carbine buffer and spring inside any carbine-buffer-tube-equipped AR-15 lower. The unit measures 9.7" long with a height of 1.1" and width of 3", and drops in without permanent modification. Purpose-built for 9mm AR-15 / AR-9 pistol-caliber builds, it gives 9mm PCC shooters a clean upgrade path for taming the harsh impulse of a direct-blowback 9mm action.
