The Trijicon Reap IR -3, in its long-range 60mm form, is a mini thermal riflescope built to reach farther into the dark than a standard thermal sight. Small, rugged, and powerful, it converts heat signatures into a clear picture so distant game and threats cannot hide behind darkness. Long-range hog and predator hunters choose the Trijicon Reap IR -3 because the larger lens pushes detection and identification out to greater distances. When your shots stretch across a big field at night, this is the thermal that keeps up.
What the Trijicon Reap IR -3 Is and Who It Is For
This is a mini thermal weapon sight configured with a 60mm lens for extended reach. It is made for hunters and operators who work wide-open country after dark, where targets appear far off and every extra yard of clarity matters. Because it detects heat rather than light, it performs where day optics go blind and where terrain offers animals plenty of cover.
The larger 60 format trades a bit of field of view for magnification and range, which is exactly the tradeoff a long-distance night hunter wants. If your typical shots are on the far edge of the field, this is the Reap IR to reach for.
Wide agricultural ground and open pasture are where this configuration earns its keep. The extra reach lets you glass a distant fence line, positively identify a sounder, and set up a shot before the animals ever sense pressure. For the hunter who covers big country, that added distance is the whole point.

- Larger 60mm lens format extends detection and identification range for distant targets.
- Rugged, compact housing engaged to shoot in any light condition.
- Redesigned electronic hardware improves system response for fast-moving scenes.
- Digital thumbstick offers intuitive control you can run by feel.
- External USB power and digital video recorder support for long nights afield.
Specifications and Build
Behind the 60mm lens sits the same high-resolution 640×480 sensor on a 12 micron pixel pitch that anchors the Reap IR line. That fine pixel pitch preserves detail as the image is magnified, which is critical when you are trying to positively identify a target far downrange. The larger objective simply gathers more of the scene’s thermal energy, feeding the sensor a stronger signal at distance.
Like the rest of the family, this unit is built to last and made in the USA. Redesigned electronics and the digital thumbstick keep the interface quick and glove-friendly in the cold. Pair it with external USB power and a recorder, and you have a complete long-range thermal solution.
Practical Use, Care, and Compatibility
Mount the scope on a rigid rail, zero on a warm target, and confirm your holds at the longer distances you actually intend to shoot. Because the reach is greater, spend time confirming positive identification before committing, and keep spare power on hand for extended sits. Store the optic in a dry, padded case and keep the lens protected from grit between hunts.
Since your shots run longer with this lens, verify your ballistic holds at real distance rather than trusting a close-range zero alone. A stable rest or bipod makes those longer shots far more repeatable in the dark. Confirm the mount torque before each outing so nothing shifts under recoil.
Complete your night rig from our wider optics collection, where mounts and accessories are ready to match this thermal. The Trijicon name means this long-range thermal was engineered to hold up to hard field use. Give it a solid mount and good fundamentals, and it will extend your effective range after dark.
For the hunter who reaches out at night, the Trijicon Reap IR -3 in 60mm form is a serious distance thermal. Ships direct to your door, no FFL required.
