Armaspec Stealth Recoil Spring 9mm G4 – AR-9 Platform

The Armaspec Stealth Recoil Spring (SRS) G4 for 9mm AR platforms replaces the standard buffer and spring assembly with a captured recoil system designed to reduce bolt bounce, smooth cycling, and quiet operation. The internal design dampens the metallic spring noise common in direct blowback 9mm builds while maintaining consistent recoil impulse for faster follow-up shots. Ideal for PCC builds and suppressed setups where mechanical noise becomes more noticeable.

The SRS G4 features a self-contained unit that installs without modification to the lower receiver or buffer tube. Engineered specifically for 9mm blowback systems, the spring rate is optimized for proper cycling with common 9mm loads. Constructed with heat-treated steel internals and a durable polymer housing. Compatible with mil-spec carbine buffer tubes. No staking or specialty tools required for installation.
