Material & Coating

Impact extruded from 7075, the PWS EBT 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.

Ratchet-Lock Design

The new 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.

Reduced Weight

Additional lightening cuts reducing weight in conjunction with the new attachment design net nearly a 1oz weight reduction from already efficient mil spec buffer tube design.

Anti-tilt Lip

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.


Featuring six stock positions with enhanced drainage ports for greater reliability regardless environment or application.

QD Mounts

The central QD sling swivel mount allows for neutral positioning of your firearm with multiple sling configurations.

    Great prisuct

    Very light, easy installation, I love the ratcheting system! No more staking the buffer tube nut! Performs well. Would recommend!

    Pricey, but convenient

    I love the concept of this buffer tube system, it's nice not having to stake anything and the QD plate is super high quality. The buffer tube is also very light, and the finish is durable. My Magpul CTR locks up tight on it. I don't mind paying for quality but it is pretty expensive for a buffer tube. Do wish they offered an A5 length but maybe that's in the works.

    Top notch product

    This buffer tube is a must have regardless of the price. I used it for my first build and I'm glad I invested it on it especially if you don't have alot of gunsmithing tools. I recommend this product if you planning a build or just upgrading.
