Armaspec Stealth Recoil Spring AR10 Gen 4 - Stainless Steel/Black, 5.7 oz - Enhanced Performance & Durability

The Armaspec Stealth Recoil Spring AR10 Gen 4 is a drop-in buffer and spring replacement engineered to transform how your AR10 handles recoil and cycles. Built for shooters who want smoother operation, less perceived kick, and a quieter running gun, this multi-stage system addresses a real pain point: the spring-on-tube rattle and wear that comes with a stock buffer setup. It's a straightforward upgrade that works on AR10 platforms without requiring gunsmithing or special tools.

At 5.7 oz in stainless steel and black hardcoat, the Stealth uses a clever two-stage spring design that keeps the buffer spring from making contact with the inner wall of your buffer tube. That isolation does two things at once—it eliminates the metallic noise and vibration that announce your shot, and it reduces the felt recoil impulse your shoulder actually feels. The buffer stays under tension against the bolt carrier throughout the cycle, maintaining consistent performance shot to shot.

If you shoot a lot—whether it's distance work, speed drills, or just putting rounds downrange—a smoother recoil impulse means better follow-up aim and less fatigue. Made in the USA and designed as a true drop-in, it's one of the easiest upgrades you can make to an AR10 without any special knowledge or tools.

Frequently Asked Questions

Is the Armaspec Stealth Recoil Spring AR10 Gen 4 a true drop-in part?

Yes. It replaces your standard buffer and spring as a complete assembly and requires no modifications to your lower receiver or buffer tube.

Will this reduce recoil on my AR10?

The multi-stage spring design is engineered to reduce felt recoil significantly compared to a standard buffer and spring setup.

What's the benefit of keeping the spring away from the buffer tube wall?

Isolating the spring from the tube eliminates spring-on-metal contact noise and vibration, resulting in smoother, quieter operation and less wear on both components.

What does "Gen 4" mean?

Gen 4 refers to the fourth generation of the Stealth Recoil Spring design and indicates this is the current production version for AR10 platforms.
