The Ozark Armament Rhino is a 1x reflex red dot sight with a 4 MOA dot that switches between red and green, with five brightness settings. It has a 28mm objective lens, fully multi-coated glass, parallax correction and unlimited eye relief. The body is machined aluminum with a matte black anodized finish, nitrogen purged and sealed against water, dust and fog. A cantilever Picatinny mount is included for co-witnessing with standard iron sights, and the sight is built to hold zero on rifles and 12-gauge shotguns. Backed by Ozark Armament's lifetime guarantee.
