Enhanced Buffer Tube
Machined from one piece of 6061 aircraft-grade aluminum, PWS engineers were able to pack more features into the PWS buffer tube.
Goodbye Castle Nut
Eliminating the castle nut, the PWS EBT’s unique indexing screw & plate system ensures secure fit and precise alignment.
Features a lip that extends into the receiver to support the back of the carrier to compensate for carrier tilt.
Unlike aftermarket items, PWS EBT QD attachments are machined directly into the aluminum for durability and weight savings.
MK1 buffer tubes are fluted, creating channels for debris, and feature four drain holes on the bottom to allow for faster water drainage.
