TLU001 Mil-Spec 6-position Receiver Extension Tube AR15

UTG Mil-Spec receiver extension tube / buffer tube replaces the factory USGI tube, fits Mil-spec 6-position stocks. Extension tube / Buffer tube will fit AR15, M16, M4 rifles with Mil-Spec 6-position stocks. The receiver extension tube is precision CNC machined from 6061/T6 aircraft grade aluminum lightweight but strong. One-piece aluminum construction with matte black anodizing finish with Mil-spec, type III hardcoat class II. This receiver tube has tightest tolerance control for zero-gap fit with polymer stocks and receivers to meet most demanding silent operations. This is Pro designe for the most serious users. Great for replaceing a worn out USGI tube, or converting a commercial carbine or fixed-stock rifle to accept an adjustable buttstock that requires the smaller, mil-spec tube. Six precision machined notches on the underside of the tube grasp the stock locking pin secure to ensure fast length adjustments without slipping. This Mil-spec 6-position stock receiver extension tube is 100% Made in USA.

This tube should be used with stocks like USGI, BCM, Colt, LMT, SOPMOD, VLTOR, Stag Arms, Magpul CTR (Mil-Spec Diameter), and others that are made to the Mil Spec dimensions.
