Sons of Liberty Gun Works Carbine-Length Gas Tube Features The Sons of Liberty Gun Works Carbine-Length Gas Tube is sized specifically for carbine length gas systems ensuring the gas port timing lines up correctly with the rest of the operating system. Its QPQ finish also known as a salt bath nitride treatment provides excellent corrosion resistance and a hardened surface that stands up to the heat and fouling generated by repeated firing. The black finish matches most mil spec builds keeping the look consistent with the rest of the upper. A roll pin ships with the gas tube giving builders everything needed to secure it into the gas block without sourcing a separate part. Because it is built to fit most mil spec firearms this gas tube is a practical option for builders replacing a bent pitted or worn original tube without compatibility concerns. Sons of Liberty Gun Works manufactures small parts intended for serious use whether that means a competition build a home defense carbine or a truck gun that sees hard use. A reliable gas tube is a small part with an outsized impact on cycling consistency so choosing a durable corrosion resistant option helps avoid stoppages down the line. This gas tube is a straightforward dependable upgrade or replacement for any carbine length AR build.
