Product benefits

The RD (Ratchet Dial) system greatly improves the rotational stability of the helmet on the head, which is very important for mounted NVGs. The user can easily adjust the harness's circumferential straps using a knob at the back of the head, ensuring the perfect fit.

The VIPER helmets have four quick adjustment buckles that allow the strap tension on the helmet to be easily adjusted for the wearer while the helmet is on the head. Belt options include leather or cotton chin straps and a plastic chin cup.

The NVG cover is made of high impact composite nylon with a CNC machined aircraft aluminum insert to which the NVG mount is attached. This ensures very tight dimensional tolerances that stabilize the NVG mount, thereby giving the carrier allow to accommodate a variety of other accessories.

Possible usage

Med-Eng ARC visors provide excellent protection against high velocity projectiles, explosive overpressure, flames, high temperatures and moisture. All models can be mounted without tools to the PASGT series and ACH series tactical duty helmets equipped with screw-on ARC rails. This is made possible via a locking pin to lock the visor in open and closed position. A special coating protects against fogging and scratching.

The four visors are named after their protective functions.
