Armaspec STLTH Recoil Spring AR10 G4 – Reduces Recoil & Noise

The Armaspec STLTH Recoil Spring G4 for AR-10 platform rifles replaces the standard buffer and spring system with a captured design that reduces felt recoil and eliminates the characteristic "twang" sound during cycling. The sealed, self-contained assembly uses progressive-rate springs that compress smoothly through the recoil stroke, helping shooters maintain sight picture and improve follow-up shot speed. This is an upgrade for shooters who want less audible noise during dry fire practice and a more refined feel during live fire.

Constructed from heat-treated steel and hard-anodized aluminum with a proprietary elastomer dampening system, the STLTH requires no lubrication and installs like a standard buffer—simply remove your existing buffer and spring, then drop this unit into the buffer tube. No gunsmithing required. Compatible with standard AR-10/.308 carbine-length buffer tubes and adjustable stocks.
