Product DescriptionThe Armaspec Stealth Recoil Spring (SRS) Gen 4 is a self-contained, multi-stage drop-in replacement for a standard AR buffer and spring, designed to deliver smoother and quieter cycling. By keeping the buffer spring from rubbing against the inner wall of the buffer tube, it helps reduce noise and friction during operation. Its second stage helps reduce felt recoil significantly, while the buffer mass is engineered to stay under constant tension against the bolt carrier for consistent performance.Product Highlights Self-contained, multi-stage Stealth Recoil Spring (SRS) Gen 4 design replaces standard buffer and spring Helps reduce felt recoil and smooth out cycling for improved shooting comfort Reduces spring noise and wear by preventing spring contact with the inside of the buffer tube Buffer mass stays under constant tension against the bolt carrier for consistent function Made in the U.S.A.Specs Brand: Armaspec Model: Stealth Recoil Spring (SRS) Gen 4 Buffer Weight Class: H2 (equivalent) Equivalent Weight: 4.7 oz (H2) Length: 7.18 in Country of Manufacture: USA UPC: 810048492701 Part Number: ARM253-H2Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
