The Armaspec Stealth Recoil Spring (brand part number ARM253-C) is a Gen 4 buffer spring built for carbine-length AR-15 builds, designed to keep the spring from rubbing against the inner wall of the buffer tube for smoother, quieter cycling. Weighing 3.3 ounces in stainless steel with a black finish, it uses an adjustable spring weight to help tune bolt carrier velocity for a given recoil system, making it a useful upgrade for shooters chasing a softer-shooting, more reliable carbine.
