The most compact configuration in the REAP-IR Type 4 family does not ask you to give up meaningful performance to get the smallest package. The Trijicon REAP-IR Type 4 24mm delivers the same improved 640x480 12 micron sensor performance, intuitive thumbstick controls, and practical reticle options as the larger REAP-IR Type 4 configurations - in the most compact and lightweight format the lineup offers. For night hunters and tactical users who prioritize minimal size and weight without abandoning the thermal riflescope capability that serious nocturnal shooting demands, the REAP-24-4 is the natural choice. The Trijicon REAP IR 24mm core is a newly improved 640x480 12 micron thermal sensor that delivers better image quality, target detection, and target recognition than previous REAP-IR generations. The REAP IR thermal scope 24mm objective keeps the overall size and weight at the minimum end of the magnified thermal riflescope category while still extracting the sensor performance needed for reliable target detection and identification at practical hunting and tactical distances. The Trijicon Thermal Scope REAP-IR Type 4 black-hot, white-hot, and edge-detect pallets give you thermal image presentation flexibility across different terrain and environmental conditions. Five user-selectable reticles cover MOA-based, MRAD-based, and bullet drop compensation reticles optimized for .223, .308, and .300 Blackout - the practical thermal riflescope reticle options that serious nocturnal hunters run in the field without any complicated programming requirements. The Trijicon REAP-IR thumbstick control operates naturally in complete darkness and with gloves on - no fumbling for small buttons during active hunting situations. The USB-C connector handles external battery pack connection for extended runtime and image and video downloads. The Q-LOC mounting system enables fast, secure attachment in multiple rifle mounting positions.
