Olight Osight SE MOS Direct-Mount Enclosed Red Dot Sight

Olight Osight SE MOS Direct-Mount Enclosed Red Dot Sight

The Olight Osight SE MOS is a purpose-built enclosed-emitter optic with a direct MOS footprint for compatible full-size GLOCK MOS slides. Its integrated mounting geometry removes the need for an adapter plate on the platforms explicitly supported by OSIGHT, keeping the optic low while preserving a sealed emitter system.

Three selectable red reticle modes

The multi-reticle system lets the user select a precise 2 MOA red dot, a 32 MOA red circle, or the combined 2 MOA dot and 32 MOA circle. This provides three sight pictures in one optic without changing the mounting setup.

• 2 MOA dot: a fine central aiming reference.
• 32 MOA circle: a larger, quickly visible reference.
• Circle-dot: combines the 2 MOA dot and 32 MOA circle.

An aspherical lens is used to support a clear, low-distortion view through the window. Brightness is adjusted from the side controls shown in the official product imagery.

Enclosed construction and side-loading CR1632 battery

The enclosed housing isolates the emitter from external dust, moisture and debris more effectively than an open-emitter layout. That construction is useful where the optic may be carried or stored in conditions that could otherwise obstruct the light path between emitter and lens.

Power comes from a side-loading CR1632 battery. Because the battery can be accessed without removing the optic from the slide, routine battery replacement does not require lifting the sight off its mounted position. Motion sensing wakes the optic when movement is detected and powers it down after three minutes of inactivity to conserve battery life.

Fit and compatibility: check before installation

This is a MOS-specific model, not the RMSc-footprint Osight SE already in the range and not the separate Osight SE DPP. OSIGHT states that the SE MOS direct-mount design is intended for compatible full-size GLOCK MOS slides.

Official exclusion: the Osight SE MOS is not compatible with Gen6 Glocks or Slimline MOS models 43X/48. Do not assume that another MOS-labelled, RMSc, DPP, RMR or aftermarket cut is interchangeable. Confirm the exact slide generation, cut, screw specification and current firearm-manufacturer instructions before installation. Fitment outside the official scope is not promised.
