The ACH Accessory Rail Connector (ACH-ARC) "ARC RAIL" is an accessory mounting system for the ACH and TC 2000, TC2001, and TC2002 series of helmets from MSA. The ARC RAIL is designed for use on MSA ACH shell sizes: medium, large, and extra large. The ARC RAIL can be mounted to a helmet with or without a cover, as per the included instruction sheet. This rail system will accommodate the use of many accessory options such as IR Illuminators, Tac-Lights, and Helmet Cameras in a stable and durable platform. Any accessory that can be mounted to a standard picatinny rail will mount to the ARC RAIL. As a safety feature the ARC RAIL mount will break away from the main rail system under stress to minimize damage to the End-User's head.
