The Ops-Core AMP Helmet Rail Mount allows for mounting to the rear of Ops-Core ARC Rails, leaving the top portion of the rails free for mounting accessories, such as lights, cameras, etc. This also creates better helmet stabilization and a counterbalancing effect of forward shroud mounted devices, such as night vision devices. A single point gimbal attachment to the ear cups allow for 360Adeg adjustment, which not only allows for better fitment and seal to the user's unique ear / head shape, but maintains that seal and moves more naturally with their head movement. Earcups rotate to the side or rear of helmet when not in use, streamlining stowage to create a very low profile.
