Reflex sight · SHIELD footprint
Mini reflex sight with a polymer lens and a 4 MOA dot in a glass-filled nylon polymer housing, 11.4 g without battery.

This version has a D-shaped polymer lens (hard-coated acrylic) and a 4 MOA (3.25 MOA) dot. The sight measures 40.8 x 25.35 x 22.8 mm and weighs 11.4 g without battery.
Thanks to the low frame and a rear iron sight notch, the weapon’s standard iron sights stay in view (co-witness).
The D-shaped polymer lens is made of acrylic and carries an anti-reflective, colour-neutral hard coating; there is no filter in front of 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.
The sight runs on a CR2032 lithium battery (3 V); Shield quotes 20,000 hours in average daylight.
The glass-filled nylon polymer housing mounts to the SHIELD footprint (over 100 mounting solutions); 40.8 x 25.35 x 22.8 mm, 11.4 g without battery.
Shield states the sight can be immersed to 0.9 m (3 ft) for 30 minutes (IP67).
Reticle
Red dot of 4 MOA (3.25 MOA): the smaller of the two dot sizes covers less of the target.
Shield specifies the dot size as 4 MOA (3.25 MOA).
The dot is produced by a red light-emitting diode, with no laser and eye-safe.
The dot adapts to the surroundings: night-vision compatible at the lowest level, visible against the sky in bright daylight at the highest.
Elevation and windage are set without click steps using the mini dial and hex wrench.
Suitable mounts and adapter plates for the SHIELD footprint; Shield lists over 100 mounting solutions. The pistol and mount are not included; M4x8 and M4x10 mm screws are supplied.
