The Olight Osight SE Enclosed Optic with RMSc Footprint and Replaceable Battery is a compact, durable red dot sight designed for concealed carry and tactical applications, ideal for pistols used in self-defense or sport shooting. For example, its 2 MOA dot and 32 MOA circle reticle provide precise target acquisition, while the motion sensor enhances battery efficiency. With a replaceable CR1620 battery, RMSc footprint, and rugged construction, it's perfect for professionals and enthusiasts. Backed by a 5-year warranty, the Olight Osight SE for Tactical Use is a reliable, versatile choice.
Precision Aiming with Motion Sensor
The Olight Osight SE features a multi-reticle system with a 2 MOA red dot, a 32 MOA circle, or both, offering 10 brightness settings (8 daylight, 2 night vision) for optimal visibility. It's powered by a single CR1620 battery, providing up to 75,000 hours (8.5 years) in the lowest daylight setting (Mode 3, dot only) or 10 years in sleep mode with the motion sensor enabled. The motion sensor activates the reticle upon movement and powers off after 10 minutes of inactivity, with a low battery indicator (flashing reticle). The optic has an IPX7 waterproof rating for submersion up to 1 meter and is constructed from 7075 aluminum for durability. The side-load battery compartment allows easy replacement without re-zeroing, and windage/elevation adjustments (1 MOA per click) support zeroing at 15, 25, or 30 yards (default 25 yards). Prolonged use in high brightness may require battery checks.
Compact and Durable Design
Crafted from 7075 aluminum with a hard-anodized finish, the Olight Osight SE is lightweight and robust, measuring 1.59 inches in length, 0.98 inches in width, and 0.97 inches in height, weighing 0.97 oz (27.5g) with the battery. The aspherical lens ensures zero distortion and parallax-free performance, with a 21x14mm objective for rapid target acquisition. The RMSc footprint allows direct mounting on optics-ready pistol slides, and its ultra-low deck height supports co-witnessing with most factory iron sights. Side buttons control power and brightness, though some users note the buttons are small for gloved hands. The design is resistant to recoil, maintaining zero after extensive testing.
Ideal for Concealed Carry and Tactical Use
The Olight Osight SE Enclosed Optic with RMSc Footprint and Replaceable Battery is tailored for concealed carry, sport shooting, and tactical users needing reliable, precise aiming. For example, its multi-reticle system suits both rapid close-range targeting and precise shots, while the motion sensor conserves battery life during carry. The side-load battery simplifies maintenance, though users should use non-permanent threadlocker (medium/blue) and torque screws to 15-17 in-lbs for secure mounting. The IPX7 rating ensures reliability in rain, but rinse with fresh water after submersion. Avoid direct eye exposure to the reticle, and ensure proper zeroing for optimal performance. With a 5-year warranty, the Osight SE offers excellent reliability, though small buttons and limited motion sensor toggle options may require adjustment.
