Experience the Pinnacle of Modular Night Vision Technology

Introducing the MOD-31 Nightfighter-MG, the lightest binocular housing on the market with manual gain control, meticulously engineered for maximum weight savings and exceptional modularity.

As a part of the MOD NODS ecosystem, the MOD-31 Nightfighter provides unparalleled flexibility, allowing users to seamlessly transition between monocular, binocular, and hybrid thermal configurations.

The Nightfighter can be configured with standard 40° arms, 55° wide field-of-view (FOV) fixed pan arms, or with the quick panning swivel arms (40° - 60° FOV).

The Nightfighter is the first and only dedicated binocular housing to ever offer panning and articulation.

Whether you’re an operator seeking a mission-specific setup or a night vision enthusiast demanding the latest innovations, the Nightfighter-MG is engineered to meet and exceed your needs.

Key Features

The MOD-31 Nightfighter-MG sets a new benchmark as the lightest binocular housing with manual gain control ever released, featuring auto shut off, IPD stops, and modularity that allows you to swap between analog night vision and thermal without any tools.

Configurable with standard 40° arms, 55° fixed pan arms, or quick panning swivel arms (40° - 60° FOV).

Ultra-Lightweight Design

This is the most lightweight binocular night vision housing with manual gain control available on the market. When paired with standard lenses and the included lightweight diopters, you have a system that is comparable in weight to the PVS-31, but with toolless modular functionality. 

When paired with lightweight lenses you can create the most lightweight binocular night vision system with manual gain control in existence.

Advanced Field of View (FOV) Options

Compatible with 40° standard FOV or 55° wide-angle FOV configurations via modular pod toppers or adjustable panning arms (40° - 60° FOV).

Swiveling panning arms allow dynamic adjustments to field of view, providing the flexibility to adapt your system to the mission.

Unmatched Lightweight Performance

At just 3.9 oz, the Nightfighter-MG housing is lighter than any other manual gain binocular housing available.

Achieve a complete system weight comparable to the PVS-31A, with the added benefit of modular functionality, using standard lenses (and included diopters). Or using lightweight lenses, you get a system with an unparalleled light weight.

Complete System Weight:

Standard Lenses	16.5 oz (PVS-31 weight)
RPO 3.0 Lenses	13.9 oz

Advanced Modular Ecosystem

Designed for maximum adaptability, the MOD-31 Nightfighter-MG is at the core of a modular system that allows users to effortlessly transform their setup:

Monocular to Binocular Configurations: Attach or detach pods using tool-free thumb screws.

Hybrid Thermal Capabilities: Swap out one pod for a thermal attachment arm or other future accessories (e.g., mini rail thermal arms).

Field of View (FOV) Options

Customize your field of view based on mission requirements:

40° Standard FOV: Traditional alignment for precise observation.

55° Wide FOV: Increase situational awareness with a fixed pan view.

40° - 60° FOV Panning Swivel Arms: Dynamically adjust the field of view for on-the-fly adaptability.

Manual Gain Control

Plug-and-Play Compatibility: Works seamlessly with standard MX-11769 image intensifier tubes—no special adapters needed.

Fully Analog rotary gain knob, instead of push buttons.

Use the centralized manual gain control knob for precise user adjustment of manual gain.

Modular Ecosystem

Designed from the ground up to be a part of a modular ecosystem, the MOD-31 Nightfighter enables the user to quickly transform their device from a monocular, to binocular, or bridged analog and thermal system-- all without the use of any tools.

Tool-Free Modularity
Attach or detach the pods from the Nightfighter bridge using the thumb screw hinge bolts—no tools required. Quickly swap between the analog night vision pods, mini rail thermal arm, or MOD-14 arms.

Auto Shutoff

The bridge supports auto shutoff on articulation, helping streamline power management.

IPD Stops
The Nightfighter bridge includes IPD (Interpupillary Distance) stops that can be fine-tuned for a comfortable viewing experience. Once set, your chosen IPD remains consistent. 

Flexible Field of View Options:
Compatible with both standard 40° and 55° wide field-of-view (FOV) configurations, or our swivel panning arms (40° - 60° FOV). Choose whichever option you prefer when ordering the housing.
