Armaspec SRS Buffer Kit BB Gen 4 – AR-15 Recoil Reduction

The Armaspec SRS (Stealth Recoil Spring) Buffer Kit Gen 4 replaces your standard AR-15 buffer and spring system with a captive multi-spring design that reduces felt recoil, eliminates buffer spring noise, and smooths out the bolt carrier cycling action. The result is faster follow-up shots, reduced muzzle rise, and a noticeably quieter rifle—especially valuable for suppressed setups where traditional buffer springs can ring like a tuning fork.

The Gen 4 kit features Armaspec's proven captured spring design with integrated buffer weight, installing directly into mil-spec carbine receiver extensions. No gunsmithing required—simply remove your existing buffer and spring, drop in the SRS unit, and reassemble. The BB (Blowback) variant is specifically tuned for direct blowback AR-15 platforms using pistol-caliber cartridges, providing the correct spring rate and buffer mass for reliable cycling. Machined from aircraft-grade aluminum with a hard-anodized finish.
