The Aero Precision AR15 Enhanced Carbine Buffer Kit (brand part no. APRH101240) pairs Aero’s Enhanced Carbine Buffer Tube with a matched carbine buffer, buffer spring, endplate, and lock nut for a complete drop-in upgrade. Carrier Support Extensions fully guide the bolt carrier group into the buffer tube after a round fires, preventing carrier tilt and reducing wear on key components, while also securing the buffer retaining pin and helping keep the tube from backing out under recoil. Position guide drain holes remove water in marine environments and smooth cycling by venting air during compression. A ramped tube design allows effortless stock installation without a screwdriver, and correctly machined thread depth keeps a fully collapsed stock from snagging on extra threads. Machined from 7075-T6 aluminum impact extrusion to mil-spec dimensions and made in the USA, this 6-position kit works with all standard mil-spec carbine stocks.
