The REAP-IR optimizes the SWAP mind set with its small packaging combined with it's lightweight features. When you need a thermal weapon sight that fits perfectly on a tactical rifle look no further as the REAP-IR will deliver. The REAP-IR system is powered by the new BAE Systems MicroIR thermal core that uses the latest 12 micron sensor technology. Now you can have a 60hz frame rate with increased magnification all in a compact military grade package.

The REAP-IR has all the features and performance of the IR HUNTER Mark Ill and the size and weight factor of the IR PATROL. The REAP-IR truly is the best of both systems incorporating a 12° field-of-view lens with the new stadiametric range finder. Having 2.5x magnification combined with the 640x480 resolution 12um micron LWIR thermal core in the small tactical package makes the REAP-IR ideal for Special Operations, Tactical Teams, border security, and night hunters.

Every REAP-IR has a 60hz fast frame rate at no addition cost. The fast frame rate will be very useful for leading a shot of a fast moving target.

The REAP-IR integrates several new features such as multiple reticle save locations so you can mount the sight on different weapons and keep your reticle position. It has the new digital read-out on the reticle adjustment screen giving you information on exactly how many clicks you have adjusted the system. With 5 different reticle patterns you can find the best fit for your application. And to finish off the REAP-IR we have added a flip-up lens cap, Mini D-LOC Rail Mount and a battery extender to every mini thermal sight.

Imagery Detailed Reticles
The REAP-IR provides you with the most clear reticles and symbols. Not only do we have the clearest image but we are doing this with MOA accuracy.

Mini DLOC Mount
The DLOC-IRD true return to zero quick release mount is a miniaturized and skeletonized variation of the very popular A4S DLOC line of optics and accessory mounts. The DLOC-IRD quick release mount is the only TRUE return to zero mount available for the IR Patrol M300w. The DLOC-IRD also grabs more rail than competing mounts, and the DLOC patented design makes it the most accurate quick release mount on the market. The DLOC-IRD can be used across multiple platforms including mil-spec, and out of spec picatinny rails without the need to adjust for tension. If you have ever wanted to move your IR Patrol on and off your weapon without the need to re-zero then this is the mount for you. With the DLOC-IRD you can now maintain true accuracy.

Stadiametric Rangefinder

The REAP-IR's stadiametric rangefinder uses a system of reticle lines with adjustable angular spacing to quickly and easily dial in on a target's distance. The REAP-IR's stadiametric rangefinding system allows you to select your target's height or width then adjust a set of reticle bars to contain your target's height or width. The REAP-IR will then give you a corresponding distance readout. Stadiametric rangefinding is widely used in long-range military sniping and is faster than laser range-finding techniques. Electronic laser rangefinders can also give away a shooters position, but a stadiametric rangefinding system is completely covert

Even in adverse weather conditions such as rain and fog the REAP-IR will still detect and identify a target. The image above was captured in dense fog with over 95% humidity.

Edge Detect ModeThe REAP-IR has an Edge Detection feature that produces an entirely different new way of viewing your target. Edge Detect mode is also a fraction of the brightness of other modes so your eyes are not as prone to night blindness after coming off the scope. There are certain tactical situations that require your display to me very dim so as not to be detected, and to reduce night blindness after coming off of your eye piece. The REAP-IR has an advanced feature that has been used on certain high end military thermal sights for years. Edge Detect gives you an entirely different way to view your target, with 90% of the screen black, and only the edges surrounding your target white. This is an extremely useful feature and is not found on any other commercially available thermal weapon sights.

Reticle Position ReadOuts  
X/Y location will give you a simple X and Y value for as many locations as you need. This means that you can set up a REAP-IR on as many weapon systems as you want and always maintain a return to zero.
MAXPOL Polarity - White Hot/Black Hot 
Most thermal weapon sights come with only one level of white hot and black hot. Some come with color pallets, but the majority of users find themselves using black hot and white hot exclusively. Rather than giving you color pallets that you will most likely never use, IR Defense designed the IR Hunter with 3 levels of white hot, and 3 levels of black hot. This allows you to choose the perfect level of polarity in the white hot or black hot modes for any situation.
ETR - Enhanced Target Recognition
The IR Hunter features an extremely beneficial technology called Enhanced Target Recognition, or ETR. Most thermal systems auto adjust the image contrast and brightness across the entire display screen. This can lead to washed out image around the crosshair or for a majority of the display area. ETR selects the are on the display to adjust leaving you with a perfectly adjusted image.
DFC - Digital Focus Control
Digital focus control allows you to not only focus your picture to the optimum setting, but it also allows sharpening of the entire picture.

    Easy to operate

    Posted by Unknown on Jun 28th 2018

    This is an excellent weapon sight. I was able to clearly identify targets at night. It is also one of the easier units to operate. The entire ordering process was simple and straight forward and the unit arrived when promised. I would definitely rent or buy from U.N.V. again.

    Amazing product, even better service from Tyler.

    Posted by Adam on May 4th 2018

    I am blown away by the quality of this optic. I have a Zeus Armasight 336 20x75 FLIR scope that I’ve been using the last couple of years and have been happy with it... but the quality of this Reap-OR is exponentially better. I am still getting familiar with all of the features but the image quality alone is worth the price. This picks up exceptional detail. That said, what I was most impressed with in the purchase was the personal care and proactive communication from Ultimate Night Vision. Tyler called me personally to walk through my order - I had actually ordered a more expensive model!.. and after understanding my needs guided me to this one... he was dead on... I was so impressed I bought a set of NVG’s from him on the same call. These guys are the rare combination of knowledgeable, priced right and exceptional in the service department. I will shop with no one else in this category from here on out. Highly recommend the Reap-IR and Ultimate Night Vision!

    REAP-IR Rental

    Posted by Todd Murphy on Jan 23rd 2018

    Great clarity but I ate threw a lot of battery&#039;s. Batteries provided only last an hour. So I switched to Duracell&#039;s and the would last 2.5 hours. Just wish it had a battery pack. Otherwise great scope. Thanks for your rental program.

    Unbelievable. After reviewing the Flir HISS at 6 times the cost and 4 times the size and weight this is top of the line for 200 meter shots. I dealt with Todd and he really knows his stuff. Great dealing with an experienced shooter and end user instead of a salesman. I would have rated the company and equipment a 10 star if it were available.
