The Wilson Combat AR-10 Buffer Spring (brand part no. TRBS10AAR10) is a round-wire stainless buffer tube spring purpose-built for .308/7.62mm rifles and carbines that need a long, heavy spring to ensure reliable cycling. AR-10-pattern rifles run a heavier bolt carrier group than a standard AR-15, and a spring that’s too light or worn can show up as sluggish cycling or short-stroking under recoil. This stainless spring is sized specifically for that heavier cycling demand, giving you consistent spring pressure shot after shot. It’s a straightforward maintenance or upgrade part for anyone running a .308/7.62mm AR-10 build.
