The MBUS Pro Sight – Rear combines rugged, all-steel construction and absolutely dependable performance into an easy-to-use windage-adjustable backup sight that’s ready when your optic isn’t. Its small size minimizes snagging, adjusts quickly, and stays exactly where you need it. With two different aperture options, shooters can quickly change between close-range/low light situations and long-range targets.
