The Wilson Combat AR-15 Enhanced Buffer Spring (Wilson Combat part no. TR-EBS15-SS) is machined from Mil-Spec 17-7 stainless round wire, delivering better rust resistance, smoother loading, and greater durability than a standard music-wire buffer spring. Wilson Combat designs this spring as a drop-in upgrade for any Mil-Spec AR-15 receiver extension, giving the bolt carrier group a more consistent return stroke shot after shot. The stainless construction resists the corrosion that eventually weakens and kinks a standard carbon-steel spring, extending service life under heavy round counts. It’s an easy, affordable reliability upgrade for anyone building or maintaining an AR-15 who wants a spring that outlasts the factory part.
