The Contractor Thermal Weapon Sight is built around our proprietary ArmaCORE™ 12 micron thermal core. It combines extensive detection capabilities and a rich, detailed picture with onboard image processing, wireless communication interface, GPS, and internal memory. The Contractor Thermal Weapon Sight is a premium-component build that is noticeably more compact and lighter weight than conventional thermal scopes. It provides up to four hours of continuous operation on two CR123 batteries—a 50% longer run-time based on lower power consumption as compared to similar units on the market.

The Contractor series also offers another first; the turret system that enables users to navigate features, such as digital zoom, color pallet and reticles quickly and intuitively to adapt to changing conditions and environments. The units come equipped with a digital compass and inclinometer that help calculate distance, direction and angles. Like all Armasight products, the Contractor is MIL-STD compliant—allowing for reliable use in all weather conditions.

    The first thing I noticed as soon as I got my hands on this was built like a tank. It's not heavy but you can tell it's all quality. The image is very clear on all magnifications and has several different color pallettes. Its very simple to use when in the field as well. You will not be disappointed.

    Robust and Easy to Use

    Posted by Jason R on Sep 11th 2023

    Let me start by saying that I have wanted a thermal scope for some time. I have a done a lot of research on various companies. What swayed me to Armasight is their customer service and professionalism. After purchase support is really important when spending this kind of money. The scope is great buy, and I would recommend it to anyone. The Image Quality is very good and has a lot of options to customize to perform in different hunting scenarios. I really like the easy record feature and the PIP mode when you zoom, really great for follow up shots.

    Great Image and Quality

    Posted by Kirk J on Sep 8th 2023

    Let me start by saying the Contractor is built with quality, it is robust and the right steps were taken to have the system waterproof. Hunting in different environments you want a product that can stand up to the challenge and work well. Image quality is great and tons of options to optimize based on the environment you are hunting in. I really enjoy the quick detach mount they include with the scope, super easy to mount and move the scope to another rifle.
