Armaspec Gen 4 Big Bore Stealth Recoil Spring

The Armaspec Stealth Recoil Spring Gen 4 in black for big-bore AR configurations such as .450 Bushmaster, .458 SOCOM, and .50 Beowulf. The captured recoil system combines the spring and reciprocating mass into a self-contained assembly for use in a compatible receiver extension.

The Gen 4 platform is available in application-specific weights and configurations, allowing builders to select the version intended for the firearm rather than using one universal recoil assembly. Gen 4 components are a distinct system and should be matched to other Gen 4 parts when servicing or changing the setup. Browse more gun parts and accessories.
