Osight Osight SE-RD Enclosed Red Dot Sight

Product Description:

The Osight SE-RD Enclosed Red Dot Sight is a compact, rugged reflex optic designed to deliver versatile performance in defensive, competitive, and everyday carry applications. Engineered on the popular RMSc footprint, this micro-sized sight provides excellent compatibility with concealed carry pistols and compact platforms without the need for adapter plates.

Featuring a multi-reticle system that includes a crisp 2 MOA dot and a bold 32 MOA circle, the SE-RD lets shooters choose the reticle configuration that best suits their engagement scenario — whether precision shots or rapid target acquisition at close range. The enclosed optic housing protects the emitter and internal components from dust, debris, and environmental exposure, enhancing long-term durability and reliability.

A side-loading battery tray allows quick and easy CR1620 replacement without ever removing the sight from the firearm, preserving zero and saving time during maintenance. With manual brightness controls, intuitive adjustments, and a clear parallax-free viewing window, the Osight SE-RD delivers dependable performance every time you mount it on your firearm.
