Impact extruded from 7075, the PWS Enhanced Buffer Tube is optimized for strength and rigidity while creating a solid platform for the new lightened design. Anodized in Mil spec type 3 to exceed standards in hardness and corrosion protection.


The patent pending Ratchet-Lock Design eliminates the need for staking the castle nut and gives a rock solid lock up while being able to remove it easily if needed in the future.


Additional lightening cuts reducing weight in conjunction with the new attachment design net nearly a 1 oz weight reduction from the PWS MOD 1 buffer tube design.


The anti-tilt lip enhances function and reliability, giving longer life to piston driven weapons by allowing the carrier to start in the buffer tube rather than transitioning into the tube on extraction.

    Ratchet lock castle nut and endplate is going on all my builds now. Not having to stake the castle nut makes installation a breeze and I have had zero issues with it staying locked in after many rounds down range. Highly recommend it!

    The PWS buffer tube and ratcheting nut have become my “go to” part for lower builds! Materials quality/design have no equal! Installation is “dummy”proof!!! So far I’ve used the PWS system on three of my heavy use builds with thousands of rounds run through them with NO issues!!! Always look to BTO for their great price on this item!
