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

The San Tan Tactical nitrided gas tube is a direct replacement component for AR-15 pistol-length gas systems. Gas tubes channel combustion gases from the barrel port to the bolt carrier group, cycling the action. This part addresses worn, damaged, or corroded factory tubes that can cause short-stroking or cycling failures. It's also essential when building a new pistol-length upper or swapping barrel configurations.

Manufactured from stainless steel with a salt bath nitride finish, this tube offers significantly improved corrosion and heat resistance compared to standard uncoated tubes. The nitriding process penetrates the metal surface rather than adding a coating that can flake or peel under sustained fire. Installation is straightforward for anyone familiar with AR-15 assembly—align the tube with the gas block and upper receiver, then secure with a roll pin. No gunsmithing or special tools required beyond a roll pin punch set.
