Unlock the full potential of your MUM-style night vision monocular. This articulating J-arm replaces unreliable proprietary mounts with the robust and common dovetail interface. It provides full articulation for stowing and switching between eyes, while completely eliminating wobble for a stable image. Get the modern functionality your NVD deserves.
BUILT FOR REAL-WORLD CONDITIONS
Standard issue J-arms often fail. They break under stress or wobble, compromising your expensive optics. This adapter is different. Designed and refined on the battlefields in Ukraine, it is built to perform without fail. We combined durable materials and smart engineering to create a mounting solution you can trust completely.
AT A GLANCE
- Upgrade to Dovetail: Securely attach your MUM-rail monocular to the most popular and reliable dovetail mounts.
- Rock-Solid Connection: Our adjustable dovetail interface connects to the mount without any play or wobble.
- Full Articulation: Quickly swing the monocular away from your eye or switch between left and right eye use.
- Compact Stowing: Folds tightly against the helmet, preventing snags and impacts during movement.
ATTENTION TO DETAIL
- Built to Last: Engineered with high-strength nylon, titanium, and brass joints to withstand hard use.
- Operator Safety: Articulating joints absorb impact energy, protecting both your device and your neck from injury.
- Perfect Eye Relief: Two adjustment points ensure perfect monocular alignment for any operator.
- Gas Mask Ready: The design can be easily adjusted to increase eye relief for use with protective masks.
