VariArc-VS Universal Helmet Light Mount for Ballistic Helmets

The VariArc-VS® helmet mount provides a full-featured, universal mounting solution for headborne illumination. The locking teeth are biased to the forward position, keeping your light aligned for the most critical uses. However, with a firm twist, the VariArc-VS mount unlocks and rotates through 8 additional lower-force index points for administrative tasks and diffused lighting options. Its small footprint and low profile keep things tidy.

The VariArc-VS includes both a Picatinny rail and a Scout light mount, allowing for maximum compatibility with visible and IR lights. The VariArc-VS is built to remain fully functional through extreme temperatures, dirt, dust, sand, water, drops on concrete, and rough handling.

The VariArc-VS Helmet Mount:

• Has high-strength hook Velcro® that provides secure attachment with a space-efficient footprint
• Includes both Picatinny rail and direct Scout light mounts
• Positively locks in the forward index position
• Directs light through 360 degrees, with 8 additional lower-force index positions
• Works in vertical positions for umbrella lighting rooms, canopy illumination, and IR strobe signaling
• Can be used in downward angles for admin & task lighting
• Has an angled pivot, allowing the user to optimize mounting for a lower profile or a more vertical rotation plane

4. Attach your light to the Scout mount using the included socket head cap screws using the included 9/64^th allen key.
5. NOTE: Verify the included socket cap screws are the correct length for your light, use your own screws as necessary.
6. Tighten the screw per the light manufacturer’s specifications
7. Mount the Velcro base to your helmet and verify rotation angles; adjust as necessary. See below for removal/repositioning.

Removal:

1. Velcro is extremely strong! Use a flat, blunt blade (large flat head screwdriver, putty knife, etc) to slide between the two Velcro layers to separate the VariArc-VS from the helmet.
2. WARNING: Removing the mount by forcefully pulling it away from the helmet may damage the helmet’s loop Velcro or separate the adhesive holding the Velcro to the helmet or the VariArc-VS.
