CMMG Gas Tube Kit Pistol/PDW w/Pin – AR-15

The CMMG Gas Tube Kit for pistol-length and PDW gas systems provides a direct replacement for worn or damaged gas tubes on AR-15 pattern rifles and pistols. Designed for firearms running pistol-length or personal defense weapon (PDW) gas systems, this kit restores reliable cycling in compact AR builds where gas tube failure can compromise function.

Manufactured from stainless steel with a natural finish for corrosion resistance and heat tolerance, this kit includes both the gas tube and roll pin for a complete installation. Installation is straightforward for those familiar with AR-15 maintenance—removing the handguard and gas block allows access for tube replacement. A roll pin punch and hammer are required to secure the tube properly. While mechanically inclined shooters can perform this swap at home, a qualified gunsmith is recommended if you're unfamiliar with gas system components.
