If you’re into firearms and pistol-mounted red dots, you’ve probably heard of Shield Sights, but not because of their optics. The name Shield is mainly associated with optic footprints. However, they are one of the pioneers in the pistol-mounted red dot market, operating since the 1980s.
Being a British company might make it easy for those in the US to overlook that they actually produce high-quality micro red dots. Their latest, the new OMSx Micro Red Dot, continues that tradition.
SPECS
The OMSx is a new optic that blends the competition-driven performance of the RMSx with the innovative translucent roof architecture of other Shield Sights models. The standard specs are as follows:
- Model(s): OMSx
- Magnification: 1x
- Footprint: SHIELD
- Dot Size: 4 MOA & 8 MOA
- Dot Color: Red
- MSRP: $489.99 MSRP
FEATURES
Shield Sights continues to advance the micro-dot category with the new OMSx, an optic that effectively combines proven competition performance with genuinely innovative design. By pairing the wide, competition-inspired viewing window of the RMSx with the translucent roof architecture first seen on the OMSsc, the OMSx provides an impressively open sight picture that feels larger, brighter, and faster than its compact size suggests.

Ambient light naturally floods the emitter and lens, while SHIELD’s always-on automatic brightness system continuously adjusts dot intensity without any user input. The result is quick dot acquisition, smoother tracking, and less visual clutter when speed is crucial.
Made from aerospace-grade 6082 T6 aluminum and rated IP67, the OMSx is built to withstand real-world use while maintaining a slim profile. With standard SHIELD footprint compatibility and multiple dot size options, the OMSx offers a thoughtful evolution for shooters aiming to maximize performance without extra bulk.
Zooming Out
This is such a new offering from Shield Sights that there’s not much available information yet. It’s almost like a soft opening for the grand opening (and if you’ve watched Ocean’s 13, you’ll get that line). The full public release will be at SHOT Show 2026.
