The Armasight Contractor 320 thermal rifle scope brings legitimate heat-detection capability to hunters and marksmen who operate in low-light or no-light conditions. Unlike traditional night vision, thermal imaging cuts through darkness, fog, smoke, and haze by detecting the heat signature of game and targets—a genuine advantage for predator hunting, search and rescue, or tactical scenarios where conventional optics fall short. This 3-12x magnification scope mounts to any standard Picatinny rail and runs on two common CR123A batteries for up to 4 hours per charge.
What sets the Contractor 320 apart from basic thermal scopes is the suite of integrated tools and connectivity options. The onboard stadiametric rangefinder, inclinometer, levelometer, and compass give you environmental data without reaching for a separate device. Eight reticle types and multiple color palettes let you dial in the view that works best for your eyes and your hunt. The 1/2 MOA boresight capability means faster zero work in the field, and the 45mm eye relief accommodates various shooting positions without forcing your head into an uncomfortable head space.
Real-world utility extends to data capture and remote viewing. Video recording and image capture save your hunt or training session to internal memory; Wi-Fi and Bluetooth 5.0 streaming lets you monitor the scope's feed on an iPhone, Android device, or other compatible gear in real time. USB-C connectivity supports future accessories and external devices. The alloy body is hardcoat anodized and sealed to IP67 waterproof standards, so it handles rain, dust, and the occasional drop without complaint.
The Contractor 320's 320x240 thermal core and 60 Hz refresh rate deliver stable, responsive imagery for dynamic shooting. Operating temperature range spans -40°F to +122°F, covering everything from high-altitude hunts to desert conditions. Recoil-rated to .50 caliber, it's built to stay zero'd on hard-kicking rifles. A cloth case and two CR123A batteries round out the package.
