Olight Osight S Fully Enclosed Rechargeable Red Dot Optic RMSc Footprint Multi Reticle Black OSIGHT S UPC 6978095650025
Product Description
The Olight Osight S Fully Enclosed Rechargeable Red Dot Optic in Black (MPN: OSIGHT-S) is an industry-defining micro reflex sight designed specifically for slimline, subcompact, and compact concealed carry pistols. Built on the widely adopted Shield RMSc footprint, the Osight S features a rugged, fully enclosed optical emitter housing that shields the internal LED from rain, mud, lint, and environmental debris—guaranteeing an uninterrupted dot projection in defensive and tactical scenarios.
Precision-machined from lightweight, high-strength OAL (Olight Aluminum Alloy), the Osight S incorporates a clear, parallax-free glass window with multi-layer anti-reflective coatings for optimal light transmission and minimal distortion. Equipped with Olight's versatile Multi-Reticle System, users can toggle seamlessly between a 3 MOA precision dot, a 32 MOA speed circle, or a combined 3 MOA dot and 32 MOA circle reticle. The unit features motion-sensing automatic wake/sleep activation (Shake Awake) and 12 brightness settings (10 daylight and 2 night-vision compatible) operated via ergonomic side push buttons.
Setting a new standard in optic power management, the Osight S features an innovative dual-recharging ecosystem. The optic houses an internal rechargeable battery charged magnetically or via the included magnetic charging cover hood. The smart charging cover acts as a portable power bank with an integrated digital battery percentage display, providing multiple full recharges to the optic without removing it from the slide. Delivering a low deck height for co-witness capability with factory iron sights, the Olight OSIGHT-S is an essential, high-reliability optic upgrade for modern EDC handguns.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct fit for pistols cut for the Shield RMSc footprint (e.g., Glock 43X/48 MOS, SIG Sauer P365 series, Springfield Hellcat, Smith & Wesson Equalizer/Shield Plus, Walther PPS/PDP F-Series). (Note: Verify optic pocket screw thread lengths; torque mounting screws using blue threadlocker to prevent loosening under reciprocating slide forces).
- Perform a complete firearm safety check: drop the magazine, lock the slide rearward, and visually/physically inspect the chamber to verify zero live rounds are present.
- Clean and degrease the optics cut area on your slide and the mounting screw holes using isopropyl alcohol.
- Place the Osight S directly onto the RMSc footprint slide cut, ensuring the recoil lugs seat fully into the bottom indexing recesses of the optic body.
- Apply a small drop of blue Threadlocker (Loctite 242) to the included optic mounting screws.
- Thread the mounting screws into the slide and torque evenly to 12–15 in-lbs using an inch-pound torque driver.
- Attach the included magnetic charging hood to top-off the internal battery until the LED percentage display reads 100%, then perform windage and elevation zeroing prior to holster staging.
