AGM Secutor LRF-C 75-640 Thermal Imaging Clip-On
AGM Secutor LRF-C 75-640 Thermal Imaging Clip-On
AGM Secutor LRF-C 75-640 is a professional thermal imaging clip-on system designed to convert a daytime riflescope into a thermal setup without changing the familiar rifle configuration. It combines a 12μm VOx uncooled focal plane array sensor, 640×512 resolution, a 75 mm F1.2 lens, true 1× magnification, and a 1024×768 OLED display, giving the user a high-detail thermal image while preserving the normal optic workflow.
The core strength of this model is its combination of long-range thermal performance and true clip-on usability. AGM states that the Secutor LRF-C can be attached in front of rifle scopes with magnification up to 10x for medium-range use, while the built-in laser rangefinder measures distances up to 1000 m with ±4 m accuracy directly in the display.
This model also includes the functions that matter in real field work: onboard video and audio recording, image capture, Shot Activated Recording, WiFi hotspot, standby mode, burn prevention, defective pixel correction, and highest temperature spot tracking. With 16 GB of built-in EMMC storage, more than 6 hours of operation from four CR123A batteries, and USB Type-C support for external 5 VDC/2 A power, the system is designed for sustained use in hunting and tactical environments.
With a detection range of 3,800 m on a 6-foot object, IP67 protection, and recoil resistance up to 1,000 g / 0.4 ms, the Secutor LRF-C 75-640 is built for users who need stronger long-range thermal detail than smaller clip-on units can provide. For Professional Optics customers, it is a premium solution with competitive pricing and delivery across Europe from Split, Croatia.

For experienced users, the main value of the Secutor LRF-C 75-640 is its ability to keep an established daytime optic setup while adding high-end thermal imaging and integrated laser ranging. The 75 mm lens and 640 core give a stronger image for long-range identification than smaller clip-on models, while the true 1× optical layout keeps the system correct for front mounting.
This is especially important in real hunting use because clip-on systems only make sense when they preserve the normal rifle ergonomics and sight picture. AGM specifically positions this model for use in front of scopes up to 10x magnification, which makes it practical for users who already have a preferred daytime optic and do not want to move to a separate dedicated thermal riflescope.
Power support is also field-oriented. Four CR123A batteries are easy to replace, and USB Type-C external power support gives the user a simple option for longer sits, static observation, or cold-weather sessions.
