JP Enterprises Enhanced Carbine Buffer Tube

This JP Enterprises Enhanced Carbine Buffer Tube revision of the standard Mil-spec buffer tube improves on the original in both design and finish. We’ve included an additional stock position (for a total of seven) and given 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 our Silent Captured Springs.

Includes buffer tube, lock ring, and lock plate.
