Midwest Industries' folding front sight tower gas block is the perfect upgrade to your AR or new retro build. Tired of always seeing your front sight through your optic? With this, those days are behind you. The MI folding front sight replaces the standard A frame used on mil-spec barrels while using an easy bolt on design. A detent button locks the sight in both the folded and deployed position. The 4140 steel and 6061 billet aluminum construction is built to last. It comes with the front sight post installed and also has a machined bayonet lug. Don't stress about install, it easily clamps onto your .750" gas journal with three screws and an allen wrench. Get that front tower out of your sight path, while still retaining the function of back-up iron sights.
