Olight Osight SE MOS Enclosed Red Dot Sight Direct Mount (OSIGHTSEMOS) optical sight

Olight Osight SE MOS — Enclosed Red Dot (Direct MOS Mount)

The Osight SE MOS is an enclosed-emitter red dot built for compatible full-size GLOCK MOS slides. It mounts directly to the MOS cut — no adapter plate — so the optic sits lower and farther rearward with fewer parts in the stack. Ideal when you want a sealed emitter and a simple, plate-free install.

Reticle & glass

• Multi-reticle: 2 MOA dot + 32 MOA circle, or switch to dot-only / circle-only
• Aspherical lens: low distortion, parallax-free window for fast acquisition
• Clear contrast for daylight and indoor work; co-witness friendly with many factory iron setups

Power & controls

• Side-loading CR1632 tray — change the battery without removing the optic (keeps zero)
• Motion sensor: wakes on movement, auto-off after ~3 minutes idle to save battery
• Long runtime on lower brightness; low-battery warning when voltage drops

Build & mount

• Enclosed emitter housing in CNC 7075-T6 aluminum
• IPX7 waterproof rating for rain and wet carry
• Native MOS footprint for compatible full-size GLOCK MOS models (e.g. G17/G19/G47 MOS Gen5-style cuts)
• Not for Slimline MOS (43X/48) — those need RMSc optics such as Osight SE / S / K
