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. 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. 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. 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.
