Primary Weapons Systems Enhanced Buffer Tube Features The Primary Weapons Systems Enhanced Buffer Tube is impact extruded from 7075 aluminum optimizing the tube for strength and rigidity while creating a solid platform for its lightened design. Anodized to mil spec type 3 standards the finish exceeds typical hardness and corrosion protection requirements for a part that sees constant contact during use. An extended carrier support lip helps the bolt carrier group start smoothly in the tube rather than transitioning in during extraction improving reliability especially on piston driven rifles. Unique fluting along the tube body assists in clearing debris keeping the buffer system running cleanly even in dusty or dirty conditions. This kit includes PWS s Ratchet-Lock castle nut and endplate set which eliminates the need to stake the castle nut while still providing a rock solid lock up that can be removed easily later if needed. Additional lightening cuts combine with the new attachment design to shave nearly an ounce off an already efficient mil spec buffer tube. The endplate features ambidextrous push button sling points giving builders flexible sling mounting options regardless of shooting hand. This Enhanced Buffer Tube kit is available for sale at GrabAGun for AR-15 and AR-308 builders who want a lightweight reliable receiver extension setup.
