Daniel Defense Rifle Length Gas Tube Assembly 04-013-09094

The Daniel Defense Rifle‑Length Gas Tube Assembly is a drop‑in gas tube sized for AR‑15 platforms running a rifle‑length gas system (commonly found on 18"–20"+ barrels). Machined to OEM tolerances from corrosion‑resistant steel and finished to resist wear, the tube provides reliable gas routing between the barrel gas port and bolt carrier, helping ensure consistent cycling and reduced receiver contamination. The kit typically ships with the installation roll pin and basic instructions for a straightforward install; professional staking and verification of headspace/operation is recommended. Ideal for builders and armorers assembling rifle‑length systems or replacing worn/incorrectly sized tubes, this assembly is a lightweight, essential component for proper gas‑system function.
