Ops-Core AMP Helmet Rail Mount Adapter Kit


  • 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 360 Degree 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.

    Amp Arms A+

    Posted by some guy on 25th Oct 2021

    The product was awesome, but thats a review on ops core. Arms unlimited website was easy to use and had an accurate "in stock" system. Shipping was fast and hassle free getting out the door and to me a day ahead of schedule. this was my first buy from arms unlimited but likely not my last.

    Shipping/ Quality

    The product I ordered was shipped and arrived much faster than I would’ve thought even though I ordered on a Saturday I still received my order on the following Tuesday. Could not be more satisfied.

    I ordered this from Gentex in four months ago and they still haven't shipped them so I bought them from AU. Exactly what I wanted

    Had trouble finding these anywhere. Arms Unliminted had them in stock and shipped them supper quick. Adapters work great with my pair of Comtacs. Would buy again.

    Great product

    These guys are on top of it. They shipped this right away. I’m using this in conjunction with AXL advanced for peltor comtac 3 and they fit perfect with my opscore sf ballistic helmet. I can now mount more stuff on the side rails like lights.

    Just do it

    Ordered this after I ordered my unity mark kit. It shipped out and was delivered before I ever even got an update from unity. Well be ordering another set for my next rig. Couldn't ask for a better headset mount for extended use.
