Sons of Liberty Gun Works Rifle Length Gas Tube – AR-15

The Sons of Liberty Gun Works Rifle Length Gas Tube is a direct replacement component for AR-15 rifle-length gas systems. This gas tube channels propellant gases from the barrel's gas port to the bolt carrier group, cycling the action. If your existing tube is damaged, corroded, or leaking, or you're building a new rifle-length upper, this tube ensures reliable gas operation for consistent cycling.

Constructed from stainless steel with a QPQ (Quench-Polish-Quench) nitride finish, this gas tube resists corrosion and heat wear far better than standard raw stainless. The QPQ coating provides a hard, slick black surface that stands up to carbon fouling and high temperatures. Installation is straightforward for anyone with basic AR assembly experience—roll pin the tube into the gas block, align it with the carrier key, and secure the gas block to the barrel. No specialized tools or gunsmithing required.
