"Designed for short-to-medium ranges, the Armasight CO-Mini GEN 2+ ID MG Day/Night Vision Clip-On System is the most compact commercially available Clip-On Night Vision Device. It uses image intensification technology and is designed to convert most low-to-mid power daytime sights, scopes, or binoculars to operate at night. It can be mounted in seconds and without tools and attached in front of a day rifle scope (using its quick release Picatinny mount) or directly onto the day scope (or binocular/ telescope) objective lens with the included adaptor. Suitable for use with most commercial and military specification day time sights, telescopes or binoculars (up to 6x magnification). Because the CO-Mini GEN 2+ ID MG is mounted in front of your own day scope, the shooters eye relief is not altered and shot release and follow through all remain intuitive. The clip-on device is factory bore-sighted to better than 1MOA accuracy, so no alteration in zero is experienced and it really is as simple as mount and shoot, just as in day time. The Armasight CO-Mini GEN 2+ ID MG is intended primarily for use by the most demanding hunter or short range assaulter, where field of view and ease of use is more important than high magnification.|Simple and quick conversion of daytime scope, sight or binoculars to Night Vision|Mounts in front of rifle scope with no re-zeroing required|Equipped with Wireless Remote Control|Auto Gain Control|Powered by a single alkaline 1.5V AA or 3V CR123A lithium battery|Low Battery Indicator|Quick Release Mount|Bright Light Cut-off System|Mil Standard Compliant"
