Osight SE Enclosed Red Dot Sight Multiple Reticles 2 MOA Dot with 32 MOA Circle RMSc Footprint Matte Flat Dark Earth OSIGHTSERDFDE UPC 6978095650520
Product Description
The Osight® SE Enclosed Red Dot Sight in Matte Flat Dark Earth (SKU: OSIGHTSERDFDE / UPC: 6978095650520) is a duty-grade, fully enclosed-emitter micro reflex optic engineered for everyday concealed carry (EDC), personal defense, and compact tactical pistols. Built on a native Shield RMSc mounting footprint with an ultra-low deck height that co-witnesses with standard factory iron sights, the Osight SE delivers all-weather reliability and rapid sight acquisition without requiring suppressor-height sights.
Precision CNC-machined from aerospace-grade 7075-T6 aluminum and finished in a matte Flat Dark Earth protective coating, the Osight SE houses its 650nm red LED emitter inside a sealed, IPX7 waterproof dual-lens chassis. Unlike open-emitter micro dots that can be obstructed by pocket lint, rain, snow, or holster debris, the enclosed emitter architecture ensures an unblocked point of aim in any environment. Its multi-coated aspherical glass lens provides a crisp, parallax-free 0.83" x 0.55" sight window with zero edge distortion, while the Multi-Reticle System lets shooters toggle between a 2 MOA precision dot, a 32 MOA speed ring, or the combined 2 MOA dot and 32 MOA circle.
Engineered for practical field maintenance, the Osight SE replaces proprietary charging hoods with a streamlined, snag-free side-loading CR1620 battery tray that enables rapid cell swaps without removing the optic from your slide or losing zero. Intelligent motion-sensing activation wakes the emitter immediately upon draw and powers down after 3 minutes of inactivity to preserve up to 75,000 hours of runtime, supported by 8 daylight settings, 2 night-vision-compatible modes, tactile side-mounted adjustment buttons, and a low-voltage flash indicator below 2.2V.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Native Shield RMSc footprint for micro-compact and slimline optics-ready slides (including SIG Sauer P365/P365XL/XMacro, Springfield Hellcat/Hellcat Pro, Smith & Wesson M&P Shield Plus Optics Ready, and Canik Mete series). CRITICAL WARNING: Will NOT mount directly to Trijicon RMR, Leupold DeltaPoint Pro (DPP), or Glock 43X/48 MOS slides without a dedicated RMSc adapter plate. Apply non-permanent medium-strength (blue) threadlocker to all mounting screws and torque strictly to OEM specifications: 15 in-lbs for M3 screws or 17 in-lbs for M4, #6-32, and #6-40 screws. Always verify screw length against the extractor plunger channel on slimline slides before torquing.
- Ensure the host pistol is completely clear, magazine removed, and chamber visually and physically verified empty before beginning installation.
- Degrease the slide optic cut, recoil bosses, and screw threads using 99% isopropyl alcohol or acetone, and test-fit the Osight SE flush against the slide deck without screws to confirm zero gap and proper recoil lug engagement.
- Select the matching thread-pitch mounting screws from the included hardware kit, verify they do not protrude into the slide extractor channel, and apply a small drop of blue (medium) threadlocker to the threads.
- Seat the optic squarely onto the RMSc footprint and torque both fasteners evenly to 15 in-lbs (M3) or 17 in-lbs (M4 / #6-32 / #6-40) using a calibrated torque driver, then witness-mark the screw heads with a paint pen.
- Confirm crisp reticle cycling (2 MOA dot, 32 MOA circle, and combined circle-dot), verify Shake-Awake activation, and zero the optic at 15 or 25 yards (1 MOA per click) prior to concealed carry or duty staging.
Key Features
- Fully Enclosed IPX7 Emitter Housing: Dual-lens sealed chassis protects the 650nm red LED emitter from lint, rain, dust, and carbon fouling for reliable all-weather carry.
- Red Multi-Reticle System (MRS): Instant toggle between a 2 MOA dot + 32 MOA circle, 2 MOA precision dot-only, or 32 MOA circle-only reticle to match distance and target speed.
- 7075-T6 CNC Aluminum Construction in Matte FDE: Lightweight 0.97 oz housing machined from high-strength 7075 aluminum with a non-reflective Flat Dark Earth finish.
- Side-Loading CR1620 Battery Tray & Motion Activation: Side-access battery compartment allows effortless cell replacement without dismounting the sight or re-zeroing, paired with up to 75,000-hour runtime.
- Distortion-Free Aspherical Glass & Low Deck Height: Multi-coated 0.83" x 0.55" aspherical lens delivers a clear, parallax-free sight picture while co-witnessing with most standard factory iron sights.
