Armaspec Gas Tube Carbine Length – AR-15 / M4 Replacement

The Armaspec Gas Tube Carbine Length is a direct replacement for worn or damaged gas tubes in AR-15 and M4-pattern rifles with carbine-length gas systems. Gas tubes are critical to cycling reliability—over time, they can erode from heat and fouling, leading to function issues. This OEM-grade replacement restores proper gas flow to the bolt carrier group, ensuring consistent cycling with factory or aftermarket parts.

Constructed from stainless steel with a durable finish to resist corrosion and heat stress. Installation requires removal of the handguard and gas block, with a roll pin securing the tube to the gas block. This is a straightforward task for shooters comfortable with AR maintenance, though a roll pin punch set and bench vise or armorer's block are recommended. Includes roll pin.
