The Armaspec Stealth™ Recoil Spring (SRS™) AR-10 Gen 4 delivers advanced recoil management and silent operation specifically engineered for AR-10 and .308 platforms. Weighing 5.7 oz, this self-contained captive spring buffer system eliminates traditional buffer spring noise while providing smooth, consistent cycling for .308 Winchester and 6.5 Creedmoor chamberings. The silent design enhances shooting comfort and focus, while the precision-tuned weight reduces felt recoil and muzzle rise for faster follow-up shots. Compatible with mil-spec carbine buffer tubes, the SRS AR-10 Gen 4 installs with a simple drop-in process—no gunsmithing required. Proper orientation is critical: the polymer bumper faces the rear, while the weight mass with O-ring faces the bolt carrier. For long-term reliability, retighten screws during routine maintenance using two 3/32" hex keys. This lightweight, high-performance buffer system is ideal for precision shooters, competitors, and builders seeking refined cycling efficiency in their AR-10 builds.
The Stealth™ captive spring design transforms the shooting experience by eliminating the metallic rattling and twanging common with traditional buffer springs. This self-contained system integrates spring and buffer into a single precision-balanced unit, operating in near silence. For AR-10 platforms—where the larger .308 and 6.5 Creedmoor cartridges produce more recoil energy—the SRS Gen 4 smooths out the impulse, reduces carrier bounce, and enhances overall comfort. The result is a quieter, more refined shooting experience that keeps you focused on the target.
The 5.7 oz weight is purpose-tuned for the demands of .308 Winchester and 6.5 Creedmoor chamberings. These larger cartridges generate more recoil and bolt carrier velocity than standard 5.56 platforms, requiring a buffer system capable of managing increased energy. The SRS AR-10 Gen 4 reduces felt recoil and muzzle rise, allowing for faster follow-up shots and improved accuracy during rapid fire. Whether you're engaging targets at distance or running competitive stages, this buffer system delivers the control and consistency precision shooters demand.
Installation is straightforward: the SRS AR-10 Gen 4 drops directly into any mil-spec carbine buffer tube. However, correct orientation is critical for proper function. The polymer bumper must face the rear of the firearm, while the weight mass with O-ring faces the bolt carrier. This configuration ensures optimal energy transfer and smooth cycling. No gunsmithing expertise is required—just insert, verify orientation, and you're ready to shoot.
For sustained performance, retighten the internal screws during routine maintenance intervals using two 3/32" hex keys or a single hex key with leverage. This simple step ensures the buffer components remain securely fastened, preserving the system's integrity over thousands of rounds. The Gen 4 design incorporates durable materials and precision engineering to withstand the rigors of high-volume shooting, competition schedules, and demanding field use.
Disclaimer: Follow all safe handling and manufacturer instructions. Ensure proper orientation (polymer bumper toward rear, weight mass with O-ring toward bolt carrier) for correct function. Verify compatibility with your AR-10 platform and buffer tube specifications before purchase.
