San Tan Tactical AR-15 Gas Tube – Nitrided Mid-Length

The San Tan Tactical nitrided mid-length gas tube is a direct replacement component for AR-15 platforms using mid-length gas systems. Gas tubes are wear items that can corrode, bend, or develop carbon buildup over time—this nitrided model offers improved corrosion resistance and durability compared to standard stainless steel tubes, making it a solid choice for shooters who maintain their rifles regularly or operate in harsh environments.

Constructed from quality steel with a salt bath nitride finish, this tube provides superior surface hardness and corrosion protection. Installation requires removal of the handguard and gas block, which most competent shooters can handle with basic tools, though a roll pin punch set and some care are necessary to avoid damaging the gas block. The tube includes a roll pin for securing to the gas block.
