Out of Stock, Backorders Ship in 4-8 Weeks

The Low Profile Rail Adapter Kit will work with most rail types such as Ops-Core ARC rails or M-LOK type rails. They allow the user to seamlessly integrate hearing protection headsets or communications systems (headset guide) directly onto helmet rails. This eliminates the need for an uncomfortable strap underneath the helmet that eventually creates hotspots and headaches.

*Important* When mounting to M-LOK, ensure the T-Nut is vertical in the slot. If it's angled there will not be enough material for the nut to hold onto causing them to pop off under strong pressure! Also ensure not to over torque the bolt and to use the included Loctite!  

Our goal when designing the low profile rail adapter kit was to create a headset adapter that minimized the overall profile of the entire tactical helmet headset system. This required the use of lightweight aluminum and glass filled nylon parts to get the strength, durability, and rotation we needed from the adapters. The end result is a ballistic helmet adapter that is 80% slimmer than the next competitor. We have recently updated the as well to feature built in wire springs to facilitate easier rotation of headsets when not in use! Along with pre-bending wires!

Great product

Great product. Recommending for all services.

Ehh definitely could be better

Bought for my Howard’s till I can get better ear pro. But they do not push down on the ears hard enough to create a seal and protect my hearing. Instal was easy. Just don’t work for actually projecting your ears with budget ear pro. I’ll know if the will work when I can get amps

Hey Cody, bend the wires in to get the seal you need! Everyone's head is different!

Easy to install

The mounts are very easy to install to the helmet (HHV Bump) and ear protection (Walkers Razor). My only issue and it's not a real problem is there's not enough tension to push the hearing protection around to my ears. Dont know if its the type of hearing protection being used that's causing the issue or not. Other then that they are well made and they do as advertised. I would still recommend for a universal adapter.


  • 3M Peltor Headsets
  • Majority of Howard Leight Earmuffs
  • MSA Sordin & most Safariland Liberator models (Requires these Adapters)
  • Most other headsets that utilize a metal wire connection to the headset.

What Comes with the Rail Adapter Kit

  • Pair (2 units) of Adapter Mounts
  • Pair (2 units) of ARC/Dovetail type rail adapters
  • Pair (2 units) Metal Wire Mounts

Installation & Use Tips

  • Wires can be bent to work for various headsets and to achieve different pressure against the side of the head.
  • The entire system rotates, so headsets can be rotated out of the way when not in use. *If you are rotating often, use a small amount of thread-locker on the bolt threads to keep the system from becoming lose*
  • They come assembled and ready to use for M-LOK type rails. If using ARC/Dovetail type rails, you will need a Hex key to switch out the back plate with the included adapter.
