The Armasight by FLIR CO-LR LRF (Clip On – Long Range) is a night vision unit that mounts in front of any existing day scope, converting the scope into a night vision-capable device with a viewing range of up to 1000 yards. Suitable for use with most commercial and military specification daytime scopes (up to 12X magnification), the CO-LR LRF can be mounted/dismounted on any standard Picatinny rail in seconds, with no special tools required. Because the CO-LR LRF can be mounted to an existing day scope, no re-zeroing is required. The CO-LR LRF allows the user to maintain consistent positioning and shooting accuracy, all while using a completely familiar day scope.

The Armasight by FLIR CO-LR LRF is intended primarily for use by the most demanding hunter or long-range target shooter, but with a build quality that makes it capable of much more. The CO-LR LRF housing is designed to take just about anything the great outdoors can throw at it. The CO-LR LRF is packed with innovative features like variable gain control, bright light shut-off, and a wireless remote control. This night vision clip-on is designed to make long-range night shooting just as easy and accurate as daytime shooting in the same terrain.

The Armasight by FLIR CO-LR LRF can be equipped with high-performance, Gen 2+ and Gen 3 variant image intensifier tubes, using Green phosphor or Armasight’s "Quick Silver" and "Ghost" filters. These provide users with natural B&W night vision images.

The Armasight by FLIR 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.

The AMRF is a pulsed laser range-finder, which uses a laser beam to measure distance. This semiconductor laser emits a wavelength of 905 nm. The range-finder allows you to measure distances of objects between 5-2000 meters away. With a rugged, lightweight composite housing, it is shock-resistant. An adjustable lever-cam clamping device ensures quick, easy, and reliable mounting and disassembly.
