Osight XE AMRS Enclosed Red Dot Sight RMR
The Osight XE AMRS Enclosed Red Dot Sight is an advanced pistol optic with a fully enclosed emitter (enclosed optic), designed for sport shooters and professional users who rely on maximum reliability in all weather conditions. The sight features the standardized RMR (Ruggedized Miniature Reflex) footprint, ensuring broad compatibility with modern optics-ready pistols and adapter plates. The sight has a total length of 4.50 cm and weighs 50 grams.
The housing is milled from high-quality 7075-T6 aluminum and offers an IPX7 waterproof rating, ensuring that the internal electronics and emitter are fully protected against rain, sand, and mud. The sight uses a multi-coated aspheric lens that provides a clear, parallax-free image with unlimited eye relief.
With the Advanced Multi-Reticle System (AMRS), the shooter can switch between four reticle patterns: a precise 2 MOA dot, a fast 6 MOA dot, a 32 MOA circle, or a combination of circle and dot. A unique innovation on the Osight XE is the Collapsible Backup Rear Sight (CBRS): an integrated emergency sight that folds out instantly with the push of a button to serve as a mechanical backup.
Power is supplied by a side-loading CR1632 button cell battery. This allows the battery to be replaced without removing the optic from the mount, ensuring that the zero point is maintained. Combined with motion activation and an automatic shut-off after 3 minutes of inactivity, the maximum battery life is up to 105,000 hours. If the voltage drops below 2.2 volts, the sight emits a warning by flashing three times briefly once per minute.
Benefits for the Target Audience
- Fully Enclosed Emitter (Enclosed Design): Sand, moisture, or gunpowder fumes cannot interrupt the LED’s beam path, ensuring consistent performance under harsh field conditions.
- Advanced Reticle System (AMRS): Offers instant selection between extreme precision at longer ranges (2 MOA), rapid instinctive firing (6 MOA), or dynamic shooting disciplines (32 MOA ring with dot).
- Integrated CBRS emergency sight: The push-button-deployable open-sight provides immediate redundancy, allowing you to continue aiming immediately in the event of a battery failure without relying on separate open-sight mounts.
- Retains zeroing settings: The side-loading battery compartment allows you to replace the CR1632 cell without unscrewing the sight or having to re-zero it.
- Extremely long operational life: Up to 105,000 hours of operational life thanks to automatic sleep and wake modes via the motion sensor.
- Wide RMR mounting base: Fits directly onto the most common pistol slides and adapters in the shooting sports and professional markets.
- Rugged 7075-T6 aluminum: Offers superior resistance to heavy recoil forces and mechanical shocks while weighing only 50 grams.
Instructions for Use and Operation
- Mounting: Mount the Osight XE on a rail or mounting plate with an RMR pattern using the appropriate mounting screws. Tighten the screws in a crisscross pattern according to the manufacturer’s specified torque.
- Zeroing: Use the elevation and windage click adjustments to precisely align the aiming point with the point of impact of your ammunition.
- Reticle and Brightness: Use the side buttons to adjust the brightness to match the ambient lighting. Press and hold the corresponding function button to switch between the 2 MOA dot, 6 MOA dot, 32 MOA circle, or the combined circle-and-dot display.
- CBRS backup sight: Press the release button on the back to pop up the fold-down sight when you want to aim mechanically. Push the sight back manually until it locks to fold it down again.
- Battery Replacement & Maintenance: Unscrew the side-mounted battery compartment, replace the CR1632 battery with the positive terminal facing outward, and tighten the compartment by hand. Clean the lenses only with an optical lens brush or a microfiber cloth.
