  • The Primary Weapons Systems® AR-15 Ratchet Lock Castle Nut / End Plate Set with Enhanced Pistol Buffer Tube was designed for optimal performance and ease of use. This buffer tube features 7075 aluminum construction with a corrosion-resistant anodized finish and is built to withstand the rigors of heavy use. Even better, the extended carrier support lip helps ensure smoother cycling while lightening cuts reduce weight compared to standard Mil-Spec designs. Fluting on the tube also provides effective debris clearing while enlarged drain holes ensure efficient drainage. If that’s not enough, this buffer tube does not require staking and can be securely installed using a castle nut wrench. Includes buffer tube, ratchet lock castle nut, and endplate.
