The Primary Arms SLx MD-25 Microdot Gen II 2 MOA Red Dot Sight delivers a clean, unobstructed view in a compact package. Built on a rugged 25mm body with a rotary brightness knob, this optic combines a crisp 2 MOA red dot with a wide field of view, giving shooters fast sight acquisition while keeping the overall footprint small on the rail. AutoLive motion-sensing technology helps preserve battery life by powering the dot down when idle and instantly bringing it back when the rifle is moved.

With true 1x magnification and generous eye relief, the SLx MD-25 Gen II is well suited for carbine range work, training, and general-purpose defensive setups where quick, both-eyes-open shooting is preferred. Its hardcoat anodized aluminum housing, fully multi-coated lenses, and enclosed emitter design support reliable performance in varied lighting and weather. Backed by Primary Arms’ reputation for practical innovation and value-focused optics, this microdot is built to be a dependable everyday companion on your favorite rifle.
