Description

I. Product Description

The FAST High Cut ARC Rail Helmet Accessories kit is a essential upgrade designed to transform your FAST High Cut helmet (XP and ST models) into a streamlined, fully-integrated tactical platform. This comprehensive rail system allows you to mount a wide range of mission-enhancing components, including ballistic visors, chinstraps, lights, and cameras, directly to the sides of your helmet.

Engineered for quick and easy replacement, these ARC rails provide multiple snag-free attachment points that facilitate rapid donning and doffing of accessories. The streamlined design allows for better routing of external wires and cables, minimizing distractions to the user. A critical safety feature is the emergency release mechanism, designed to release accessories at 8 ft-lbs (11 Newton meters) of torque to prevent neck injuries in the event of snagging. Constructed from durable, lightweight materials, this kit includes two FAST High Cut ARC Railsmounting hardware (22mm ballistic screws) , and bungee cords for a complete installation solution.
