Mako Tactical Meprolight M21 D4 reflex sight provides instant, all-light aiming capability, without batteries. Designed through close collaboration with Israeli Special Forces, the M21 is battle proven, simple to use accurately and totally reliable.

The M21 offers a large 30mm diameter lens which allows rapid target acquisition with both eyes open. This was the first reflex sight in the world designed for close quarter combat, and it comes with a 4.3 MOA dot reticle.

Illumination of the aiming point is achieved by a fiber optic collector system during the day, and by a miniature self powered tritium light source at night. Transition between the two systems is instantaneous and automatic to assure good contrast between the aiming dot and the target area.
