Armaspec Stealth Recoil Spring H2 G4 – High-Performance Buffer System for AR-15 Rifles

The Armaspec Stealth Recoil Spring H2 G4 is a drop-in buffer and spring replacement engineered to smooth out your AR-15's action and tame recoil impulse. If you're tired of the mechanical noise and felt kick of a stock setup, or you're looking to fine-tune your rifle's reliability and handling for everything from precision shooting to tactical drills, this multi-stage recoil system offers a thoughtful alternative to factory components. It's one of those upgrades that makes you actually notice the difference in how your gun cycles and shoulders.

What sets the Stealth Recoil Spring apart is its design philosophy: it keeps the buffer spring from chattering against the inside of your tube, which cuts down on noise and wear. The multi-stage spring design is tuned to reduce felt recoil without sacrificing reliability, and the buffer mass geometry maintains steady pressure on your bolt carrier throughout the cycle. It's a straightforward drop-in swap—no gunsmithing needed—and it's built in the USA, so you know the engineering and tolerance stack are dialed in.

This is the kind of component that appeals to shooters who want a quieter, smoother-running rifle without chasing extreme specs or adding complexity. Whether you're running suppressed or unsuppressed, or you just want less muzzle rise and less punishment on your shoulder during a range session, the H2 G4 is a sensible middle-ground upgrade that plays well with most standard AR-15 builds and ammunition.

Frequently Asked Questions

Will this buffer system work with my AR-15?

The Armaspec Stealth Recoil Spring H2 G4 is designed as a drop-in replacement for standard AR-15 buffer tubes and is compatible with mil-spec AR-15 rifles. No modifications to your lower receiver or tube are required for installation.

Does this really reduce felt recoil?

The multi-stage spring design is engineered to reduce felt recoil compared to stock buffer-and-spring setups. The H2 designation indicates a specific weight and spring rate tuning. Results will vary depending on caliber, ammunition, and your rifle's overall configuration, but many shooters notice a noticeable difference in both recoil impulse and muzzle rise.

What's included in the box?

The Stealth Recoil Spring H2 G4 is a complete buffer and spring assembly. It replaces your standard buffer tube contents and is ready to drop in as a self-contained unit.

Is this system quieter than a stock buffer?

One of the design features is that the internal geometry prevents the spring from rubbing against the inside of the buffer tube, which reduces mechanical noise and friction compared to standard setups. The result is a smoother, quieter cycling action.
