San Tan Tactical AR-15 Gas Tube – Nitride, Carbine Length

The San Tan Tactical AR-15 gas tube routes combustion gases from the gas port to the bolt carrier group, cycling the action. This nitrided carbine-length tube is a direct replacement for worn, damaged, or corroded factory gas tubes. Upgrading to a nitrided tube provides superior corrosion resistance and durability over standard stainless steel tubes, particularly in high-volume shooting or harsh environments.

Constructed from heat-treated steel with a black nitride finish for maximum resistance to fouling and erosion. Drop-in installation—no gunsmithing required. Fits standard carbine-length gas systems (approximately 7.5" tube length). Gas tube roll pin not included.
