Features in practical use
Square glass lens
The square, filter-free glass lens with colour-free anti-reflective coating gives a clear image; the housing is machined from aluminium.
Co-witness
The hollow bridge design allows co-witnessing with standard iron sights; adjustment is without click detents.
Nitrogen-sealed, IP68
Nitrogen-sealed housing, submersible to 9 m (30 ft) for 30 minutes (IP68).
Automatic brightness
Brightness adjusts automatically, so the sight can stay on; the lowest level is night-vision compatible.
Side battery compartment
Side access; choose CR2025, CR2032 or CR2050 for longer runtime or a narrower, less obtrusive build. 20,000 hours in average daylight with a CR2032.
SHIELD footprint
Mounts to the SHIELD footprint (more than 100 mounting solutions), aimed at narrow-frame and single-stack pistols for EDC and concealed carry.
Reticle
4 MOA
Red dot of 4 MOA (3.25 MOA).
Automatic brightness
Brightness adjusts automatically; the range runs from night-vision compatible to visible against a bright sky.
Filter-free view
Square glass lens without filters; the anti-reflective coating is colour-free and keeps the visible signature low.
Eye-safe
The light source is a red LED, not a laser; no radioactive materials.
