Material & Coating

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.

Ratchet-Lock Design

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.

Reduced Weight

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.

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.

  1. Great quality product! Easy to install and looks really good. Fit and function is flawless.

    *This product is not compatible with the American Defense Manufacturing UIC lower receiver. The extended lip on the buffer tube will conflict with a raised section on the ADM UIC lower receiver.

  2. excellent product. first one I purchased had improper threads but within a week I had a new one. excellent service and great product

  3. Great product. Easy install and worked perfectly with my Magpul STR. Will be buying more.

  4. When will we see a PISTOL version??? IMHO should have rolled out when this one did……c’mon P.W.S.

    I have to say this is a really impressive piece. As a mechanical engineer I attest that the design, machining, and attention to detail is first rate. Worth the price.

    My only criticism is the shipping label. I would prefer that it did not say “Primary Weapon Systems” on the outer shipping label. In these times, I like to keep a low profile when it comes to receiving gun parts at home and at work.

    Upgraded to one of these on my Daniel MK18 — I wanted something a touch lighter and higher quality, and I also own a couple PWS rifles so expected some top shelf stuff. Wasn’t disappointed, and it’s completely worth it.

    I’m so happy with it I’ll probably buy at least one more, maybe 2. Heads up on your stock — mine was an amazingly tight fit for but doesn’t rattle around anymore like a maraca!

  7. (verified owner)

    Looks great and different. Mine had minor pits and machine marks. Should have been better polished before coating. Pissed off that a 100 castle nut and buffer tube isn’t near perfect. Not worth my time to send back. Hurt the value of the company for future orders

    • Hi Garrett, Our MOD 2 Enhanced Buffer Tube is machined from an impact extrusion. The impact extrusion is at the finished diameter, so the areas on the tube that are not machined may show marks that are typical for impact extrusions. Our finished buffer tubes are 100% inspected for cosmetic and functional flaws, and passed or failed based on what customers’ feedback has been, as well as comparison to competitors’ products. We feel confident that our product is the best it can be, but if you’d like to return it because you are unhappy please give our customer service team a call. They’ll be happy to get the buffer tube back from you and refund your money. Thanks, PWS
