San Tan Tactical AR-15 Gas Tube – Nitride Rifle Length

The San Tan Tactical nitride gas tube is a direct replacement for worn or damaged AR-15 gas tubes in rifle-length gas systems. Gas tubes are high-wear components subject to carbon fouling and heat stress—replacing a compromised tube restores reliable cycling and prevents gas leaks that cause short-stroking or failure to eject. This is a maintenance part every AR owner should keep on hand.

Manufactured from stainless steel with a nitride finish for corrosion resistance and reduced friction. The nitride treatment extends service life compared to standard stainless tubes. Installation requires gas block removal and a roll pin punch—straightforward for anyone comfortable with basic AR maintenance, though a properly staked gas tube roll pin is essential for reliability.
