OSight SE MOS: enclosed Glock MOS red dot

[Moondog]

OSight gave me a rare opportunity to test an optic before it was released to the public. The SE MOS is a modification of the SE designed to fit exclusively on MOS-cut Glock slides. This pre-release sample fits 9mm Glock slides; a 10mm and .45 versions are in development.


This new SE mounts directly onto a Glock MOS slide, allowing it to co-witness to factory iron sights. It molds and fits onto a Glock slide like it was made to be there. The SE MOS retains the SE's multi-reticle 2 MOA dot and 32 MOA sunburst circle. It upgrades the side-tray battery to a CR 1632, giving it a whopping 120,000 maximum battery life!


OSight expects to release the MOS sometime in August 2026 at a similar price point as the standard SE model.

100% These OSights are a bargain for what they are. Though I hear some folks have had durability issues, I haven't had a problem with any of mine.
