Miniature Collimating Sight

The Armasight MCS (Miniature Collimating Sight) is a micro LED Collimating Sight for “both-eyes open” rapid target acquisition. The MCS is rugged, lightweight and designed to mount onto many existing optics as well as MIL-STD 1913 Picatinny and Weaver-style rails.

The Armasight MCS is the only sight on the market in its class that features a dual reticle pattern. The user can select a 3.5 MOA “Dot” reticle or 20 MOA “Ring” reticle pattern depending on mission requirements. The MCS is compatible with night vision devices of all generations. Reticle intensity is regulated by an automatic brightness control sensor (which can be overridden by the user to maximum brightness mode if so required).

The MCS is designed to significantly improve accuracy and efficiency of virtually any weapon, from handguns and pistols, to assault rifles and light machine guns. The compact size and versatility of the MCS makes it an ideal secondary/backup optical sight. Accurate and reliable, the Armasight MCS features 1.2 MOA/click windage and 1.5 MOA/click adjustments. A unique optical design allows for parallax-free “always on the center” reticle.

Waterproof; tested against salt fog, dust, vibration, drop-tested, and fired on a variety of firearms for thousands of rounds.

The MCS features a unique pivot lens cover with anti-reflective coating and works on a single, easy to replace CR2032 3V battery.
