The Olight Osight S is a compact open-emitter reflex sight built on the industry-standard RMSc (Shield RMS) footprint. It is designed for slimline, compact and subcompact pistols used for concealed carry, tactical shooting and hunting.
The multi-reticle system lets you switch between:
- 2 MOA Dot
- 2 MOA Dot + 32 MOA Circle
- 32 MOA Circle only
This gives you a fine aiming point for precision or a larger circle for fast target acquisition.
Power comes from the built-in 46 mAh rechargeable battery plus the Magnetic Charging Cover. The cover charges the optic (full charge in about 1.5 hours) and extends runtime. Battery life is up to 21,900 hours on the lowest daylight setting (dot only) and up to 87,600 hours with the charging cover.
The 21 × 14 mm window is sized for slim slides. Adjustments are 1 MOA per click with ±35 MOA travel. The housing uses OAL proprietary aluminum alloy with Level III hard anodizing. The optic is IPX6 water-resistant; the charging cover is IPX4.
