Overview

The Osight 3 MOA is the original pistol red dot the Phoenix-based Osight brand launched at NRAAM, an open-emitter reflex sight on the RMR footprint with the company's signature magnetic charging cover. The reticle is a single 3 MOA dot, available in red or green, sized for precision shooting at typical defensive and recreational distances rather than the close-quarters speed of a 6 MOA dot.

Power is rechargeable. The optic carries a built-in Li-Po cell and snaps a magnetic charging cover with its own power bank onto the top of the housing for off-pistol top-ups. The cover doubles as a battery-state indicator. Construction is aluminum housing with an aspherical lens that Osight rates as parallax-free across the working distance band of a duty pistol.

Footprint is Trijicon RMR, fitting most full-size and compact MOS slides including Glock 17/19 MOS, SIG P320, and S&W M&P 2.0 Optics-Ready platforms. At $229.99 the 3 MOA sits at the same price as the larger-window MRS-equipped Osight X, which makes the X the obvious upgrade for buyers prioritizing window real estate or reticle flexibility. Choose the original 3 MOA when a clean single-dot sight picture is preferred over a circle-dot stack.
