The Armaspec Stealth Recoil Spring Carbine G4 is a self-contained buffer and spring replacement engineered to transform how your AR-15 carbine cycles. Unlike standard buffer setups, this drop-in upgrade uses a multi-stage design that isolates the spring from the buffer tube wall, eliminating the noise and friction that comes with conventional systems. If you've ever heard that metallic rattle or felt your shoulder absorb more recoil than necessary, the G4 addresses both problems in one unit.

The Stealth Recoil Spring works by keeping constant tension on the bolt carrier throughout the cycle, which smooths out the action and noticeably reduces felt recoil. The second-stage spring design is the key—it cushions impact differently than a single-spring buffer, absorbing energy more effectively over a longer stroke. Drop it in where your current buffer and spring live; no gunsmithing required. This is the kind of upgrade that pays for itself in comfort if you're shooting volume through a carbine, whether that's training, competition, or a long day at the range.

Made in the U.S.A., the G4 is built to the same standards Armaspec has earned in the AR community. It's a solid choice for shooters who want a quieter, softer-shooting rifle without replacing the entire stock or going to an expensive piston system.

Frequently Asked Questions

Is the Armaspec Stealth Recoil Spring compatible with my AR-15 carbine?

Yes, the G4 is designed as a drop-in replacement for standard buffer and spring setups in carbine-length AR systems. Simply remove your existing buffer and spring and install the Stealth Recoil Spring—no modifications required.

How much does the Stealth Recoil Spring reduce recoil?

The multi-stage spring design and engineered buffer mass are specifically tuned to reduce felt recoil significantly compared to standard buffers. The exact reduction depends on caliber, barrel length, and load, but shooters consistently report noticeably softer shooting with the G4.

Will the Stealth Recoil Spring make my rifle quieter?

Yes. By keeping the spring separated from the buffer tube wall, the G4 eliminates the metallic rattle and friction noise that comes with standard setups, resulting in smoother, quieter operation overall.
