Windham Weaponry has developed a solid steel Gas Block with an integral Picatinny Rail allowing you to mount the accessory front sight of your choice. This Gas Block will replace your existing front sight/gas block on 3/4” diameter barrels by slipping it on and tightening the supplied set screws. It has a pre-drilled gas path hole, gas tube hole and gas tube spring pin hole, and includes the Windham Weaponry “WW” machined into the front face. The beauty of using a rail mount front sight is the ability to remove it when you choose to shoot with a scope or optics. This rugged unit is machined from solid billet, bead blasted, and then black manganese phosphated for a durable non-reflective surface.
