Armaspec Stealth Recoil Spring 9 G4 - High-Performance Recoil Management System

The Armaspec Stealth Recoil Spring 9 G4 is a drop-in replacement buffer and spring system designed to improve how your rifle handles recoil and operates. If you're running a standard setup and tired of a punchy shoulder, inconsistent cycling, or that rattle from spring-on-tube wear, this multi-stage recoil management system addresses all three—without swapping your upper or receiver.

What sets the G4 apart is its engineering approach: the spring is separated from the buffer tube wall, eliminating the metallic rub that wears on your tube and creates unwanted noise. Meanwhile, the multi-stage design works to reduce felt recoil noticeably, and the buffer mass is kept under constant tension against the bolt carrier for more predictable, controlled lockup. Drop it in where your standard buffer and spring go—no gunsmithing needed.

Made in the U.S.A., the Stealth Recoil Spring 9 G4 is built for shooters who want smoother operation, less wear, and a noticeable decrease in shoulder punch on the range or in the field. Whether you're fine-tuning a duty gun, dialing in a hunting rifle, or just tired of clatter in the tube, this is a straightforward upgrade that works.
