SOLGW MID LENGTH GAS TUBE QPQ

Description

Sons of Liberty Gun Works built this mid-length gas tube for AR-15 builders and owners who want a reliable, properly finished component rather than a bare-metal aftermarket piece. The mid-length gas system ports gas from the barrel at a point that gives the bolt carrier group more time to travel before pressure begins cycling the action, compared to a carbine-length setup. That additional dwell time translates to a softer felt impulse and reduced wear on the bolt and buffer system over time, which matters on a rifle that sees regular use.

The tube is constructed from stainless steel, which resists the corrosive effects of propellant gases that pass through it during firing. SOLGW then applies a QPQ finish over the stainless — a salt bath nitride process that further hardens the surface and adds a second layer of corrosion resistance without building up material that could affect fit in the gas block. A roll pin is included, so the tube is ready to install without a separate hardware order. For anyone refreshing a worn gas tube or assembling a mid-length upper from scratch, this is a direct, uncomplicated solution from the manufacturer that produces the rifles these components were designed around.
