Compact reflex sight · single-stack pistols
Compact aluminium reflex sight for single-stack pistols with a glass lens, only 23 mm wide and 16.2 g without battery, with 4 or 8 MOA in black or Flat Dark Earth.

The dot is available as 4 MOA (3.25 MOA) or 8 MOA (6.5 MOA), as Shield specifies the dot sizes, each in black or Flat Dark Earth (FDE). Only the selected version is supplied.
The low profile allows co-witnessing with the standard iron sights; with Shield’s matching low-profile Glock MOS plate (not included), Shield states no suppressor-height sights are needed.
According to Shield the glass edition has a scratch-resistant, very clear glass lens and revised electronics with improved battery contacts; the D-shaped lens has no filter dimming the image.
The sight adjusts its brightness itself and can therefore stay on permanently; the lowest level is night-vision compatible, the highest is visible against the sky in bright daylight.
A CR2032 lithium battery (3 V) gives 20,000 hours in average daylight according to Shield; it sits on the underside and the sight is removed to change it.
Machined from aerospace-grade aluminium and only 23 mm wide, mounted on the SHIELD footprint (over 100 mounting solutions according to Shield); 40.8 x 23 x 22.8 mm, 16.2 g without battery.
Shield states the sight can be immersed to 0.9 m (3 ft) for 30 minutes (IP67).
