Armaspec Stealth Recoil Spring, 9mm Gen 4

The Armaspec Stealth Recoil Spring (brand part number ARM253-9) is a Gen 4 buffer spring built for 9mm AR-platform builds, designed to keep the spring from rubbing against the inner wall of the buffer tube for smoother, quieter cycling. Weighing 6.4 ounces in stainless steel with a black finish, it uses an adjustable spring weight to help tune bolt carrier velocity for a blowback 9mm action, making it a useful upgrade for shooters chasing more reliable cycling and less muzzle bounce.
