Shield Sights OMSX Mini XL 4 MOA Glass Lens Reflex Sight

The 4 MOA dot is the middle ground in reflex sight aiming points. It is larger and easier for the eye to catch under stress or in poor light than a 2 MOA dot, and it still holds enough precision for practical shooting distances - four minutes covers roughly four inches at 100 yards, which stays well inside vital zone territory out to normal range.

The sight itself is the Shield Sights OMSX in the Mini XL size with a glass lens. It is an open reflex design, so the emitter fires forward onto a single lens and the shooter looks through an open window rather than a tube. The Mini XL body gives a bigger viewing window than a standard mini reflex while keeping the compact profile that lets these sights work on pistol slides and low rifle mounts without dominating the gun.
