Thermal Clip-On That Works | Armasight Operator 640 Night Hunt Review

Night hunting just got way easier. The Armasight Operator 640 thermal clip-on transforms your daytime rifle setup into a night-ready predator rig—without changing your zero.

Lightweight, simple to mount, and surprisingly intuitive, this thermal optic attaches directly in front of your LPVO (1-4x, 1-6x, 1-8x) and lets you detect heat signatures out to 1300 meters. Whether you're chasing hogs or coyotes, it’s got everything you need: video recording, multiple color palettes, and recoil tolerance up to .50 BMG.

We tested it multiple times—off, on, and back again—and zero stayed locked. Clear edges, solid contrast, and smooth operation even in pitch-black conditions. No re-zeroing needed. No guesswork. Just results.
