TNVC does a quick presentation of the Ops-Core Power Path Rail to manage cables that carry power to helmet mounted devices... "The days of needing to Dremel your Ops-Core helmet rails are gone! The new Ops-Core Power Path Rail is a natural progression of an already great rail system for head mounting. New features include a cable management channel that allows you to secure and protect your NVG auxiliary power cables, preventing snags or damage or having to use tape or Velcro or other improvised methods of securing cables, and is fully compatible with all FAST SF accessories, including mandibles or other rail accessories. This rail is available first as a standard option on the new Ops-Core FAST BUMP, while rolling out into other existing models in the future, as well as being available for individual upgrade purchase soon."
