Aim Sports RT5C1 Compact Reflex Sight Matte Black 1x27mm 3.5 MOA Red Dot

The compact red dot reflex sight is small enough to mount on a pistol and yet large enough to use comfortably on a rifle as a CQB option. It features a single side activation button for fast activation, 1 MOA adjustment per click, integrated Weaver-style mounting system and control of the illuminated red dot with six levels of brightness.
