A corrosion-resistant all-steel back-up sighting option is the MBUS Pro (Magpul Back-Up Sight). Including rail-height gas blocks, the dual aperture, windage adjustable rear and no-tool, elevation adjustable front are the best mounting options for 1913 Picatinny rails. Positive detents keep the MBUS Pro Rear low when stored and at regular AR sight height when it is deployed. The steel rectangular site post’s match or standards width options are available, and the sight is case-hardened and coated with Melonite QPQ for extremely high wear- and corrosion-resistance.
