Sons of Liberty Gun Works Pistol Length Gas Tube QPQ – AR-15 Pistol Builds

The Sons of Liberty Gun Works Pistol Length Gas Tube is a replacement component for AR-15 pistol-length gas systems. This tube channels gas from the barrel port to the gas key on the bolt carrier group, cycling the action. Upgrading to a quality gas tube ensures reliable function and prevents failures caused by worn or corroded OEM parts.

Constructed from stainless steel with a QPQ (Quench-Polish-Quench) nitride finish for corrosion resistance and longevity. The QPQ treatment provides a hard, low-friction surface that resists wear and extreme temperatures. Installation is straightforward for builders with basic armorer tools—gas tube roll pin punch and hammer required. No gunsmithing needed for drop-in replacement on standard AR-15 pistol-length gas systems.
