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 precise alignment of the buffer tube.
Featuring a lip that extends into the receiver to support the carrier, the EBT eliminates any present 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 several drain holes to allow water to escape the system.
PWS H2 & H3 Buffer
Low contact points allow debris to fall into channels, while Nickel Teflon coating keeps carbon from sticking. PWS machinists engrave the PWS logo directly into the 4140 steel.
