The Trijicon EO REAP353 Reap-IR 35-3 is a compact thermal rifle scope built to put targets in your sights regardless of light, weather, or darkness. This is a purpose-built thermal optic for hunters and precision shooters who need to see heat signatures when conventional glass falls short. The 640x480 sensor at the heart of the system delivers the thermal resolution and image quality that makes the difference between a clean detection and missed opportunity, paired with 1.75–14x magnification and an 8x digital zoom for flexible ranging and engagement.
Trijicon engineered the REAP-IR as a genuinely field-ready tool. The 35mm objective and compact footprint keep weight manageable at 26.5 ounces while the aluminum housing stands up to the punishment of real use. The redesigned electronics and digital thumbstick respond faster than earlier versions, and the system now accepts external USB power alongside standard CR123 batteries—a practical advantage on longer operations. Eye relief of 27 inches gives you plenty of room for proper cheek weld and scope positioning. You get a QLOC mount in the box, USB-C cable, video adapter, batteries, hard case, and all the documentation you need to get running immediately.
Built in the USA, the scope operates reliably from deep cold to summer heat (–25.6°F to 122°F) and shrugs off water immersion to 1 meter. The 30 Hz or 60 Hz frame rate options let you dial the refresh rate to your power budget and viewing preference. Whether you're hunting predators in the dark, conducting night operations, or evaluating distant targets in fog or smoke, the REAP353 gives you a thermal advantage without the bulk of larger systems.

The scope ships with a QLOC (quick-detach) mini Picatinny rail mount. The QLOC system allows tool-free mounting and removal from any standard Picatinny rail. The mount is included in the box. For specific rifle platform recommendations or alternative mounting solutions, consult your firearm's manual or contact a gunsmith.
A single CR123 battery provides approximately 2 hours of runtime. The scope ships with two CR123 batteries. You can also connect an external USB power source via the USB-C port to extend operation indefinitely in the field, which is especially useful on longer missions or when using the higher 60 Hz frame rate.
The REAP353 arrives with a mini Picatinny rail mount (QLOC), USB-C to USB-C cable, inline analog video adapter, user manual, quick reference guide, two CR123 batteries, shuttered eye guard, hard carrying case, warranty card, and a LensPen for lens care.
