Bull Craft Fixed-Aperture NVG Infinity Focus Caps

Designed and manufactured by Bull Craft Industries, the Fixed-Aperture NVG Infinity Focus Caps are engineered to minimize the need for constant objective lens adjustments while maintaining a broad, usable focal range. Once installed, the caps allow your night vision device to remain focused from just a few feet away to effectively infinity, helping you spend less time refocusing and more time observing your surroundings.

The precision-engineered fixed-aperture design is optimized for immediate use and requires no tuning or adjustment. Install the caps once and enjoy consistent performance with no moving parts to adjust, loosen, or inadvertently change in the field.

Whether navigating changing environments, transitioning between near and distant objects, or simply reducing unnecessary optic adjustments, the Fixed-Aperture NVG Infinity Focus Caps provide a practical upgrade for compatible night vision systems. By extending the usable depth of field, they help streamline operation without permanent modifications to your device.

Precision manufactured using industrial SLS PA12 nylon, the Fixed-Aperture NVG Infinity Focus Caps combine exceptional durability with minimal weight. The tool-free slip-on design installs in seconds using a precision friction fit—no screws, clamps, adhesives, or modifications required. Each cap features an integrated flip-up protective cover retained by a low-profile bungee tether, keeping the covers attached while allowing instant access to your optics when needed.

The low-profile design adds virtually no noticeable weight or bulk while maintaining a streamlined profile. A disruptive textured exterior helps reduce reflections, provides additional grip, and complements the appearance of modern night vision systems. The black dyed finish is ready for paint or Cerakote to match your equipment.
