Carbine-length stainless steel gas tube for AR-15 builds chambered in .223 Remington and 5.56 NATO. The tube routes gas from the gas block back to the gas key on the bolt carrier, formed with the correct bends and dimensions for a carbine gas system. Measures roughly 9.75" — the standard carbine length used on 14.5" and 16" barrels with carbine-length gas ports.

Features:

• Carbine-length gas tube, approximately 9.75"
• Stainless steel construction for heat and corrosion resistance
• Correct bend geometry for a carbine gas system
• Includes gas tube roll pin location on the front for standard front sight base or low-profile gas block attachment
• Direct replacement — no cutting or filing

Gas tube length must match your barrel's gas port location. A carbine-length tube pairs with a carbine-length gas port (roughly 7" from chamber). Verify your barrel's gas system before ordering — a mismatched tube will not clear the receiver front.
