CMC Triggers AR-15 Gas Tube – Carbine Length

The CMC Triggers AR-15 Gas Tube in carbine length delivers reliable gas system operation for standard carbine-length AR-15 builds and replacements. This gas tube channels propellant gases from the barrel's gas port to the gas key on the bolt carrier group, cycling the action for semi-automatic fire. Replace worn or damaged tubes, or use when building a custom upper receiver with a carbine-length gas system (typically paired with barrels 10–18 inches).

Manufactured from stainless steel with a Melonite finish for corrosion resistance and heat tolerance. Installation requires disassembly of the upper receiver and removal of the handguard—a roll pin punch and basic armorer's tools are necessary to remove the old gas tube roll pin and install the new tube. This is a standard drop-in component for builders and armorers familiar with AR-15 assembly.
