CMMG Gas Tube Kit Carbine with Roll Pin – AR-15 Mid-Length

The CMMG Gas Tube Kit provides a factory-spec replacement gas tube for carbine-length AR-15 gas systems. This kit is essential when building a new upper receiver or replacing a worn, damaged, or corroded gas tube that's causing cycling issues. The gas tube channels high-pressure combustion gases from the barrel's gas port back to the bolt carrier group, ensuring reliable semi-automatic operation.

Manufactured from 304 stainless steel with a corrosion-resistant finish, this tube is built to withstand sustained heat and gas exposure. The kit includes a stainless steel roll pin for securing the tube to the gas block. Installation requires basic gunsmithing tools: a roll pin punch set, hammer, and gas block alignment. While mechanically inclined shooters can complete this as a drop-in replacement, proper alignment is critical for function and safety.
