Armaspec Gen 4 AR-15 Stealth Recoil Spring Kit

The Armaspec® Gen 4 AR-15 Stealth™ Recoil Spring is a self-contained multi-stage drop-in replacement for standard AR-15 buffers and springs. The SRS™ is designed to keep the buffer spring from rubbing against the inner wall of the buffer tube for smooth and quiet operation, while the second stage reduces felt recoil for improved reliability. Better yet, the buffer mass is designed to stay under constant tension against the bolt carrier for consistent operation and reliable performance. Compatible with most Mil-Spec receivers and buffer tubes. Made in USA.
