Armasight Contractor 640 Thermal Rifle Scope - 3-12x50mm, Multi-Reticle, 640x480 Resolution, 1x-4x Zoom, Black Hardcoat Anodized

The Armasight Contractor 640 thermal rifle scope is a compact, feature-rich thermal optic built on Armasight's proprietary ArmaCORE 12-micron thermal core. Whether you're pursuing hogs at night, doing precision long-range shooting in low-light conditions, or running tactical drills, this 3-12x50mm scope delivers the detection range and image clarity needed to perform when conventional optics fail. At under 2 pounds and engineered for recoil up to .50 caliber, the Contractor 640 handles serious firearms without the bulk or weight of traditional thermal weapon sights.

The real advantage of the Contractor 640 lies in its balance of capability and usability. The intuitive turret-based control system lets you quickly dial through color palettes, digital zoom (1x–4x), and eight reticle options without taking your eyes off target. You get onboard intelligence too: a digital compass, inclinometer, levelometer, and built-in stadiametric rangefinder help you calculate distance, angle, and wind hold. The 640x480 AMOLED display delivers sharp, detailed thermal imagery with active on-screen graphics, and the 1/2 MOA boresight adjustment ensures reliable zero repeatability out of the box.

Battery life is a genuine strength here. The Contractor 640 runs up to four hours on two CR123A cells—roughly 50% longer than comparable units—with a low-battery indicator to keep you aware in the field. Video recording and image capture are built in, with USB, Wi-Fi, and Bluetooth 5.0 connectivity so you can stream to iOS or Android devices or offload footage for analysis. All of this is sealed to IP67 and rated for sustained operation from –40°F to +122°F, so the scope won't quit in harsh conditions. The package includes a quick-detach mount, thermal zeroing target, batteries, and a soft case to get you running immediately.

This is a serious thermal option for hunters, shooters, and operators who demand precision and reliability without compromise. The Contractor 640 doesn't waste features on marketing—every tool on board serves a real job in the field.
