JP Enterprises Enhanced Carbine Buffer Tube


This JP-SPEC revision of the standard Mil-spec buffer tube improves on the original in both design and finish. They've included an addition 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 their Silent Captured Springs.


Includes buffer tube, lock ring and lock plate



  • Addition stock position stop compared to standard Mil-spec 6-position design
  • Extra fine internal finishing for smoother, quieter cycling and reduced buffer component wear
  • High quality exterior finish for reduced buttstock friction

  • Fully Mil-spec compatible
