Armaspec Stealth Recoil Spring H3 G4 – AR-15

The Armaspec Stealth Recoil Spring H3 G4 is a drop-in replacement for standard AR-15 buffer and spring assemblies, designed to reduce noise, vibration, and felt recoil. This captured spring system eliminates the metallic "twang" of mil-spec buffer springs while providing H3-weight buffering for smooth, consistent cycling. Ideal for shooters who want a quieter, smoother-running carbine without modifying the lower receiver or buffer tube.

The G4 generation features a precision-machined buffer body with an internal captive spring system that requires no external spring or retaining pin. Installation is simple: remove your existing buffer and spring, drop in the Stealth Recoil Spring, and reassemble. Works with standard carbine-length buffer tubes. The H3 weight (approximately 5.4 oz) is well-suited for carbine-length gas systems with mid-weight barrels or suppressed rifles.
