WMD Guns Pistol-Length Gas Tube Features The WMD Guns Pistol-Length Gas Tube is processed using WMD s Nitromet treatment which hardens the surface of the tube while giving it a rich deep black color. That nitride finish adds meaningful durability compared to an untreated gas tube helping the part resist the heat and carbon buildup that gas tubes are regularly exposed to during firing. Sized specifically for pistol length gas systems this tube is a direct fit for AR-15 builds using that gas system length whether building from scratch or replacing a worn factory tube. The finish also helps the part blend visually with other black AR-15 components for a cohesive build. WMD Guns packages the gas tube together with a roll pin giving builders everything needed for assembly without having to source a separate pin. This attention to completeness reflects WMD s broader approach of offering plated finished components ready to drop into a build rather than leaving customers to track down small hardware separately. As a company built around in house metallurgy chemistry and plating expertise WMD Guns applies that same quality control to smaller parts like this gas tube as it does to its complete uppers and chassis. The WMD Guns Pistol-Length Gas Tube is available for sale at GrabAGun for AR-15 builders working on a pistol length platform.
