This JP Enterprises Enhanced revision of the standard Mil-spec buffer tube improves on the original in both design and finish. JP included an addition stock position (for a total of seven) and gave the tube a finer surface finish for smoother function. This design is also designed to allow extra threading into the receiver, which optimizes protrusion for use with the Silent Captured Springs. Includes buffer tube, lock ring and lock plate.
