CMC Triggers AR-15 Gas Tube – Mid-Length

The CMC Triggers AR-15 Gas Tube channels propellant gases from the barrel's gas port to the bolt carrier group, cycling the action. This mid-length tube is a direct replacement for worn, damaged, or fouled factory tubes, restoring reliable function in AR-15 platforms with mid-length gas systems. Mid-length systems are common on 14.5" to 18" barrels and offer smoother recoil impulse compared to carbine-length systems.

Constructed from stainless steel with a corrosion-resistant finish for durability under repeated high-temperature gas exposure. Installation requires disassembly of the handguard and removal of the gas block—basic armorer-level work with standard tools. The tube includes a roll pin for gas block attachment.
