Bootleg Gas Tube Features The Bootleg Gas Tube is built from stainless steel for corrosion resistance and consistent performance under the repeated heat cycling a gas system experiences during firing. Sized for a mid length gas system the tube routes propellant gas from the barrel s gas port back to the bolt carrier group to cycle the action. A silver finish gives the tube a clean factory correct appearance inside the upper receiver. The included roll pin secures the tube properly to the gas block during installation so no separate hardware purchase is needed. Bootleg builds its parts and accessories using premium materials intended to outlast lower quality alternatives which matters for a part as critical to reliable cycling as the gas tube. A correctly fitted gas tube is essential for consistent bolt carrier timing making this a sensible component to source from a trusted maker rather than an unknown import. The mid length configuration suits common 16 barrel AR-15 builds striking a balance between felt recoil and reliable cycling. This Bootleg Mid-Length Gas Tube is available for sale at GrabAGun for AR-15 builders and owners performing maintenance.
