The TacFire A2 Complete Stock Kit for AR-15 (brand part number MAR123) fits standard Mil-Spec AR-15 lower receivers with a fixed, A2-style profile. The kit includes a rifle-length receiver extension tube, A2 buffer, buffer spring, spacer, and screw, so the whole rear assembly arrives ready to install in one box. A hinged butt plate opens into an internal storage compartment for batteries or small spares, and TacFire molds the whole stock from durable, impact-resistant polymer built to handle range and duty use.
