CMMG Carbine-Length Gas Tube Kit, Stainless Steel

The CMMG Carbine-Length Gas Tube Kit (brand part number 55DA193), part of CMMG’s Build & Replace line, is a 9.75-inch stainless steel gas tube sized for a carbine-length AR-15 gas system. It ships with the installation roll pin needed to complete the swap, so a builder or armorer has everything required to replace a bent, pitted, or worn carbine-length tube in one part. CMMG specifically notes this tube will not fit mid-length or rifle-length barrel gas placements, so it is important to confirm gas system length before ordering. The stainless construction resists corrosion better than a plain steel tube over repeated heat cycling.
