Primary Weapons Systems .308 Enhanced Buffer Tube

    Primary Weapons Systems recently released their new Enhanced Buffer Tube for ARs chambered in .308 Winchester. Their new EBT in .308 is compatible with standard AR-15 buffers and is machined from one piece of 6061 aircraft-grade aluminum. It eliminates the use of a castle nut with a unique indexing screw and plate setup to ensure correct alignment with the buffer tube. The PWS EBT also features QD attachments machined directly into the tube as well as fluted sides and drain holes to allow water to escape. One downfall to early piston designs for the AR-15 was carrier tilt. The EBT features a lip that extends into the AR receiver that supports the carrier and eliminates carrier tilt making it a great option for piston driven ARs. There’s no official word on a price as of yet, however their other Enhanced Buffer Tubes retail for $149.95 to $199.95. Check out PrimaryWeapons.com for more info.
