Armaspec SRS AR9 G4 9mm Recoil Spring System
Armaspec's drop-in SRS G4 recoil spring reduces felt recoil and keeps the buffer spring from rubbing the tube. Multi-stage design with rubber O-ring prevents metal-on-metal contact. Made in the U.S.A. with lifetime warranty.

Armaspec SRS AR9 G4 Recoil Spring System
The Armaspec Stealth Recoil Spring (SRS) G4 is a self-contained, drop-in replacement for your standard AR-15 buffer and spring assembly. Engineered specifically for 9mm AR platforms, this system delivers measurable improvements in recoil management and operational smoothness.
Key Features
- Multi-stage design reduces felt recoil significantly
- Rubber O-ring on the buffer mass head eliminates metal-on-metal contact
- Prevents spring rubbing against the inner buffer tube wall for quiet, smooth operation
- Constant tension design keeps the buffer mass under continuous pressure against the bolt carrier
- Drop-in installation compatible with standard AR-15 carbine-length buffer tubes
- Made in the U.S.A. with lifetime warranty
Installation Details
The SRS comes pre-assembled with Red Loctite on the front metal stop and Blue Loctite on the bottom bumper. When reassembling, we recommend reapplying Loctite to ensure proper retention. The system installs with or without a buffer retainer—the polymer bumper faces the rear of the firearm, while the weighted mass with O-ring faces the bolt carrier.
Why It Matters
If you've experienced the harsh recoil impulse of a 9mm AR or noticed spring noise during operation, the SRS G4 addresses both issues. The multi-stage spring rate and precision-engineered buffer mass work together to smooth out the firing cycle while keeping your rifle running quietly and reliably.
