The CMMG Pistol/PDW Gas Tube Kit (brand part number 55DA15F) is a 6.75-inch stainless steel gas tube sized for a pistol-length AR-15 gas system. It ships with the installation roll pin needed to complete the swap, so a builder has everything required to replace a bent, pitted, or worn pistol-length tube in one part. The stainless construction resists corrosion better than a plain steel tube through repeated heat cycling in the short gas system a pistol or PDW-length build relies on.
