The Daniel Defense Mil‑Spec 6‑Position Receiver Extension (Buffer Tube) is a rugged, drop‑in carbine‑length receiver extension designed to fit AR‑15/M4‑pattern rifles that accept mil‑spec tubes. It provides six detented stock positions for reliable length‑of‑pull adjustment and features the standard mil‑spec internal diameter (1.148 in / 29.16 mm) for compatibility with mil‑spec stocks and buffer assemblies. Built for hard use, the tube is precision‑machined for concentricity and finished to resist corrosion and wear; Daniel Defense typically uses heat‑treated 7075‑T6 aluminum with a hard‑coat anodized finish for this class of part, giving a strong yet lightweight mounting point for the buttstock. Ideal for military, law‑enforcement, or civilian builds where MIL‑SPEC fit, repeatable geometry, and durable construction are required.
