The Sons of Liberty Gun Works (SOLGW) 13.65" Intermediate Gas Tube is a premium rifle component specifically sized for intermediate-length gas systems. It is constructed from high-quality stainless steel and treated with a QPQ (Quench-Polish-Quench) salt bath nitride finish, which provides superior corrosion resistance and a harder surface for a longer service life. This black finish also helps the tube remain visually inconspicuous under slotted handguards. The tube is engineered to ensure reliable gas flow and consistent cycling for professional-grade AR-15 and AR-10 builds.
