Description
The UTG Pro TLU001 is a Mil-Spec 6-position receiver extension tube (buffer tube) for AR-15 rifles and carbines. It is the precision-machined backbone that accepts any standard Mil-Spec diameter carbine buttstock on an AR-15 lower receiver, giving the shooter a full range of length-of-pull adjustments along the buffer/spring stack.
CNC machined from a single piece of 6061-T6 aircraft-grade aluminum, the TLU001 features precisely rolled threads for durable, repeatable engagement with the lower receiver threads, along with a matte black Type III hardcoat anodized finish for long-term corrosion and wear resistance. The tube is built to the standard Mil-Spec 1.148″ diameter, so it is a direct drop-in replacement for factory Mil-Spec carbine receiver extension tubes and fits all common Mil-Spec carbine stocks and compatible accessories.
The 6-position detent design locks the stock at six distinct length-of-pull settings, letting you dial in a comfortable fit for your body type, kit, or shooting position. This listing is for the receiver extension tube only; the buttstock, buffer, buffer spring, castle nut, and lower receiver are not included.
