The Spikes Tactical Mil-Spec Carbine Buffer Spring (part no. SLA501S) is a direct replacement for the spring that drives your AR-platform carbine buffer back into battery after every shot. Spikes Tactical makes it from 17-7 stainless steel and finishes it with an electro-polish that gives it a smoother look and feel than a standard blued or phosphated spring. Built to mil-spec dimensions, it’s a drop-in fit for any standard carbine-length buffer tube, whether you’re replacing a worn factory spring or building from scratch.
