The Burris Thermal Rifle Scope USM S35 640 V3 is a 640x480 thermal optic built for serious night hunters who demand real performance in low-light and no-light conditions. This isn't entry-level thermal—it's a purpose-built hunting tool that combines a high-resolution 12-micrometer pixel pitch sensor with thoughtful engineering to eliminate the guesswork when the sun goes down. The S35 640 V3 puts thermal imaging within reach for hunters ready to expand their season and hunt smarter in darkness.
What sets this scope apart is the balance between capability and usability. Burris's Cybercore technology drives a 640x480 resolution sensor with a 50 Hz refresh rate, delivering the thermal clarity you need to identify game at distance. The 35mm F1.0 lens opens wide to gather heat signatures efficiently, while the 7.8° × 5.9° field of view gives you enough context to scan terrain and locate targets without tunnel vision. Ten customizable reticle options let you dial in the sight picture that works for your style of hunting.
Power management is practical: dual 18650 batteries (one internal, one hot-swappable) run for over 5 hours per charge, and USB-C charging means you're never hunting for an outlet. The rotary dial interface responds intuitively even in complete darkness, so you spend more time glassing and less time fumbling with menus. Add video recording and real-time streaming via the BurrisConnect app, and you can document your hunt or troubleshoot gear from your phone. The scope includes an American Defense Manufacturing quick-detach Picatinny mount with adjustable cantilever for drop-in compatibility on most modern rifle platforms. IP67 waterproofing and an 800G shockproof shutter ensure it handles rough field work without complaint.
This is thermal optics for the hunter who wants results, not marketing hype.

Frequently Asked Questions
Can I use the Burris S35 640 V3 thermal scope on any modern rifle?
The scope includes an American Defense Manufacturing quick-detach Picatinny mount with adjustable cantilever, which fits any M1913 rail system. This covers the vast majority of modern hunting rifles, ARs, and tactical platforms. If your rifle has a Picatinny rail, you're ready to go.
How long does the battery last on a single charge?
The dual 18650 battery system—one internal and one hot-swappable—provides over 5 hours of runtime. You can swap the replaceable cell without powering down the scope, and the internal cell can be charged while the scope is in use, extending your hunting time on longer trips.
What's included with the scope?
The Burris Thermal Rifle Scope USM S35 640 V3 comes with the American Defense Manufacturing quick-detach M1913 Picatinny mount with adjustable cantilever. The mount is ready to attach to any standard rail on your rifle.
Does this thermal scope work in complete darkness?
Yes. The thermal sensor detects heat signatures rather than visible light, so it performs equally well in complete darkness, fog, light rain, and other conditions where conventional optics fail. The 50 Hz refresh rate and 640x480 resolution deliver clear imaging of game heat signatures at hunting distances.
