Armaspec SRS-H Stealth Recoil Spring AR-15 Gen 4 3.8 oz Buffer

The Armaspec Stealth Recoil Spring (SRS) in the Gen 4 Heavy (H) configuration is a self-contained, multi-stage drop-in buffer system designed as a direct replacement for the standard carbine buffer and recoil spring in AR-15 platform rifles.

Rated at an equivalent weight of 3.8 oz (Heavy), the complete SRS-H system weighs 6.6 oz and measures 7.18" in overall length. The unit is built from steel for long-term durability, delivering enhanced recoil control and smoother cycling compared to a conventional buffer and spring setup.

Designed as a true drop-in replacement for AR-15 carbine-length buffer tubes, the Armaspec SRS installs without permanent modification, making it an ideal upgrade for shooters seeking more consistent felt recoil and improved reliability across varying ammunition loads.
