ATN ThOR 4 640 Thermal Rifle Scope, 2.5-25x, 640×480

ATN ThOR 4 640 2.5-25x Features and Performance

The ATN ThOR 4 640 2.5-25x is a premium thermal rifle scope built for hunters, landowners, and serious nighttime shooters who want strong thermal image quality, versatile magnification, and modern digital tools in one optic. Built around a Gen 4 640×480 thermal sensor, this model delivers a noticeable step up in detail over lower-resolution thermal scopes, making it a compelling option for predator hunting, hog hunting, nighttime property work, and other after-dark shooting applications where better image quality can make a real difference.

One of the biggest strengths of the ATN ThOR 4 640 2.5-25x is its broad 2.5-25x magnification range. That spread gives shooters a useful balance between scanning and more deliberate target observation, letting the scope work across a wide variety of distances and hunting environments. Whether you are checking field edges, watching open ground, or taking a closer look at distant heat signatures, this model is designed to give you more flexibility than a fixed-purpose thermal optic with a narrower zoom range.

ATN built this ThOR 4 on its Obsidian IV Dual Core platform, which helps separate it from a more basic thermal riflescope. The scope includes ATN’s Smart Range Finder, Ballistic Calculator, Smooth Zoom, Recoil Activated Video, and built-in wireless connectivity. For buyers who want more than raw thermal detection, these features add real practical value by helping with ranging, shot management, recording, and general field usability.

The ATN ThOR 4 640 2.5-25x also uses a 1280×720 HD display and supports 1280×960 video recording, helping provide a cleaner digital viewing experience while making it easy to capture footage directly through the optic. Built-in Wi-Fi and Bluetooth add convenience for connecting to compatible devices, managing settings, and sharing recordings. ATN also rates the scope for 18+ hours of continuous battery life, which is a major advantage for long hunts, overnight setups, and extended use in the field.

For customers looking for a high-performance thermal riflescope with a premium 640-class sensor, strong magnification range, and advanced onboard features, the ATN ThOR 4 640 2.5-25x is a compelling choice. It offers the thermal performance needed for serious nighttime use while also delivering the smart digital features that have made the ThOR 4 line especially popular with hunters who want a more capable all-in-one thermal optic.
