Sons of Liberty Gun Works QPQ Coated Carbine Length Gas Tube CARBINEGASTUBE

The Sons of Liberty Gun Works Carbine Length Gas Tube is a professional-grade rifle component designed for AR-15 and AR-10 platforms using carbine-length gas systems. It is crafted from premium stainless steel and treated with a QPQ salt bath nitride finish, which provides a harder, more corrosion-resistant surface compared to standard phosphate coatings. This finish also creates a smooth black appearance that matches other nitrided components while reducing carbon and fouling buildup. Engineered to Mil-Spec standards, it serves as a durable drop-in replacement or a reliable choice for new duty-grade builds.
