The Armasight CO-LR-LRF (Clip On – Long-Range) is a night vision unit that mounts in front of an existing day scope and converts the day scope to night vision capability up to ranges of 1000 yards. Suitable for use with most commercial and military specification day time sights, telescopes or binoculars (up to 12X magnification), the CO-LR-LRF can be mounted/dismounted on a standard Picatinny rail in seconds, and with no tools required. Because the CO-LR-LRF is mounted in front of your own day scope, the shooter's eye relief is not altered, and shot release and follow through all remain intuitive – because the unit is factory bore-sighted to better than 1MOA accuracy, no alteration in zero is experienced, so it really is as simple as mount focus-shoot, just as in day time.

The CO-LR LRF can be used with an Advanced Modular Range-Finder (AMRF2200). The AMRF2200 is designed to determine the exact distance between the observer and the target, and works with any NV Clip-On system that includes an LRF option. Measurements are displayed on the range-finders indicators and in the FOV of any connected NV device.
