The ARGUS PVS-31 (Gen 2 IIT) is a high-quality, fully functional replica of the legendary PVS-31 night vision binocular, equipped with Generation 2 Image Intensifier Tubes. Built with an ergonomic, low-profile design, it delivers significantly enhanced situational awareness compared to standard monoculars.

Conceptually, this model is a hybrid of two widely popular systems: the L3 AN/PVS-31 and the Act in Black DTNVG. It inherits its housing, core functionality, and ergonomics from the PVS-31, while utilizing the versatile and widely available PVS-14 objective optics concept from the DTNVG.

Key Features & Design Advantages

• Optimized Weight Distribution: The housing mounts are shifted backward, positioning the center of gravity closer to the helmet. This prevents the need to extend the mount forward to its maximum, drastically reducing neck strain.

• Durable Construction: Crafted from high-grade polymer that matches the look, feel, and tactile experience of the original PVS-14 housing.

• Premium Optics: Fitted with PVS-14 lenses featuring precision threading. The Infinity Focus Lock Rings include a flathead setscrew for secure, slip-free locking.

Ergonomics & Power Management

• Controls & Auto-Shutoff: The power button is conveniently located above the battery compartment. Power-on requires a long press (approx. 1.5–2 seconds). Features an automatic shutoff function when flipped up on a Rhino Mount.

• Power Options:

  • Powered by a single AA battery.

  • The battery compartment cap is made from the same lightweight polymer to minimize overall mass.

  • Equipped with a dedicated power port on the right side of the housing, compatible with the original L3HARRIS Battery Power Supply and aftermarket equivalents.

• Custom Interpupillary Adjustment: Dual set-screws located at the bridge connection points allow precise interpupillary distance alignment within a range of ±4–5 mm per side.
