Sons of Liberty Gun Works Rifle-Length Gas Tube Features The Sons of Liberty Gun Works Rifle-Length Gas Tube directs propellant gas from the barrel back to the bolt carrier group cycling the action on rifle-length gas system builds. Its QPQ treated finish provides strong corrosion resistance helping the tube withstand the heat and fouling that comes with repeated firing cycles. A corrosion resistant gas tube matters most on rifles that see heavy use where untreated components can degrade and eventually cause cycling issues. The included roll pin means the gas tube arrives ready for installation without needing to source a separate fastener. Sons of Liberty Gun Works builds its small parts to fit most mil-spec firearms so this gas tube drops into a wide range of rifle-length AR builds without special fitting. Finished in black it matches the appearance of most mil-spec finished rifles while blending in rather than standing out. Builders replacing a worn bent or damaged gas tube can rely on this part to restore proper function to a rifle-length gas system. The Sons of Liberty Gun Works Rifle-Length Gas Tube is available at GrabAGun for builders and armorers maintaining mil-spec AR-platform rifles.
