Olight Osight SE | RMSc Footprint Enclosed Red Dot Sight with RMR Adaptor

Olight Osight SE | RMSc Footprint Enclosed Red Dot Sight with Replaceable Battery and RMR Adaptor

The Olight Osight SE RMSc Footprint Enclosed Red Dot Sight is engineered for concealed carry pistols, subcompacts, and low-profile builds. It features a fully enclosed emitter, a crisp 2 MOA center dot with optional 32 MOA circle, and three selectable reticle modes—dot-only, circle-only, or circle-dot. Using the standard RMSc footprint, it mounts directly to many optics-ready slides without aftermarket modification, ensuring quick integration for EDC and defensive pistols.

Built for clarity and reliability, the Osight SE employs an aspherical lens that offers parallax-free aiming and enhanced light transmission. With ten total brightness settings—eight for daylight and two for night vision—the reticle remains visible in all conditions. Adjustments are made in precise 1 MOA increments, supporting accurate zeroing for both defensive and training use.

Power is provided by a side-loaded CR1620 battery, enabling replacement without disturbing zero. The optic is housed in rugged 7075-T6 aluminum and sealed to IPX7 standards, protecting against rain, debris, and incidental submersion. Weighing less than 1 oz, it adds minimal bulk while withstanding the recoil of centerfire handgun calibers. The low-profile design ensures fast presentation from concealment with a snag-free draw stroke.

The optic window measures approximately 0.83 × 0.55 inches, striking a balance between speed and precision. The sight maintains zero under repeated firing cycles and is field-tested for durability in daily carry environments. With its compact form and advanced features, the Osight SE is well-suited to modern concealed carry pistols.

Included with this purchase is the Olight Osight RMR to RMSc Adapter Plate, expanding mounting flexibility. This precision-machined SUS420 stainless steel plate allows RMSc-footprint optics to be installed on slides cut for the larger RMR pattern. Treated with a matte black PVD finish for corrosion resistance, the adapter maintains a secure fit under recoil while adding just 14 grams of weight. Measuring 45.2 mm × 25.5 mm × 4.3 mm, it preserves slide balance and co-witness potential while offering full structural integrity.

The RMR to RMSc Adapter Plate is compatible with the Osight SE, Osight S, and other RMSc-pattern optics such as the 407K, 507K, and EPS Carry. Installation is straightforward with included screws and a torque-compatible tool, ensuring proper alignment and long-term durability. This addition gives shooters the flexibility to run enclosed RMSc-pattern red dots on slides originally cut for RMR optics without requiring a new slide or additional machining.

Every package includes the Osight SE enclosed red dot sight, CR1620 battery, installation screws, adjustment tool, user manual, and the RMR to RMSc Adapter Plate. Make sure to check compatibility, manual, and other resources before purchase. Together, these items deliver a versatile and durable optics solution for concealed carry or duty use, giving shooters a reliable red dot system with expanded compatibility right out of the box.
