The Osight SE MOS is the industry’s first enclosed-emitter red dot sight built with a direct MOS footprint. It mounts straight onto compatible full-size GLOCK MOS slides without an adapter plate, sitting lower over the bore and closer to the shooter’s eye.

The multi-reticle system lets you switch between:

• 2 MOA Dot
• 32 MOA Circle
• 2 MOA Dot + 32 MOA Circle

This gives you a fine aiming point for precision work or a larger circle for faster target acquisition. An aspherical multi-coated lens provides a clear, low-distortion, parallax-free sight picture through a 21 × 14 mm enclosed window.

Battery changes are simple. The side-loading CR1632 tray lets you replace the cell without removing the optic, so your zero stays intact. Maximum runtime is up to 140 000 hours on Mode 3 with the 2 MOA dot only. A motion sensor turns the sight on with movement and shuts it down after 3 minutes of inactivity. Brightness memory recalls your last setting, and a low-battery warning appears when voltage drops below 2.2 V.

There are 10 brightness settings (8 daylight + 2 night-vision). The housing is CNC-machined from 7075-T6 aluminium and rated IPX7. The low deck height is designed to co-witness with factory-height iron sights on compatible MOS slides.

Compatible Weapons Direct mount (no adapter plate) on compatible full-size GLOCK MOS slides, including:

• Glock 17 MOS
• Glock 19 MOS
• Glock 45 MOS
• Glock 47 MOS
• Other standard full-size MOS models such as G20 MOS, G21 MOS and G26 MOS (MOS cut required)

Not compatible with:

• Glock Gen 6 models
• Slimline MOS pistols (G43X MOS / G48 MOS)

The Osight SE MOS is built for EDC, defensive use and training on standard full-size GLOCK MOS pistols where a low, enclosed, plate-free setup matters.
