Overview
A red dot sight built for the Glock Modular Optic System cutout, using a 4 MOA dot on a 23mm lens. Its flat profile sits low enough on the slide to co-witness with factory iron sights rather than sit raised above them.
Because it mounts inside the slide cut instead of on a raised plate, the sight keeps a lower profile than typical red dot mounts, which is what allows co-witness with stock sights. Brightness adjusts automatically with a manual override, and the housing is aircraft aluminum. Parallax is fixed at 25 meters.
- 4 MOA red dot on a 23mm lens
- Built for direct fit to Glock MOS slides
- Automatic brightness control with override
- Parallax-free at 25 meters
Who it's for
Pistol owners running a Glock MOS-cut slide who want a low sight that co-witnesses with the factory irons. Not usable on a non-MOS slide without a separate mounting plate.
Pros and cons

- Automatic brightness with manual override
- Aircraft aluminum housing

Performance notes
The 4 MOA dot is a middle size, small enough for aimed shots and large enough to find quickly on the draw. Automatic brightness control tracks ambient light, with the manual override there for lighting the sensor misreads. The optic is also listed as compatible with night vision, laser, and thermal add-ons.
