Breath of fresh air

I have been using helmets now for a couple of years, My first being from HHVT and now the second gen plus this comms adapter all for recreation that moved into legitimate duty use in tactical EMS operations. 1st) the installation of this into their rail system is like any other M-lock attachments one might be using on a weapon platform. So there is no new proprietary system that will make you buy a bunch of other items just to get the damn thing working. That earned a star. 2nd) Holy hell are they sturdy. I’ve bumped into things not accidentally and on purpose to test them and they didn’t budge an inch. On top of the fact that they hold your comms to your head and keep a great seal even with head movement. Another star. 3rd) light weight and very “high speed, low drag” for us larpers out there who have the Gucci gear to perform ops in our parents basements. Another star. 4th) For what you get with these, the price is unbeatable. Extremely cost effective and amazing “bang for your buck” quality. Plus, veteran owned company. Another star. Finally, 5th) After I bought these and had been using them for a while, HHVT sent me a personal letter in the mail along with a “Protector” patch, thanking me for my purchase and what not. Not only was this incredibly nice of them to do this, it shows that as a company, they care. It could have been a generic pre-written letter sent via email or in the mail like everyone else. Nope, not HHVT. Hand written thank you letter. 5 stars all round.

Must Have Item!

Having a set of ear pros permanently attached to your helmet just makes sense. I'm running a set of Howard Leight Impact Sport BOLTS, and at first, I had the adapters mounted to the very top, single section, of the MLOK rail. I wasn't getting a perfect seal on the back of my ear, so I dropped the adapters down to the middle of the lower, triple section. Problem solved. They rotate easily enough, but you still have to use some force, which is a good thing. Keeps them tight against your head, or against the back of the helmet. No need to go looking for ear pros, or wearing an uncomfortable band under the helmet.

Rail Adapter Kit -Fits ARC, Peltor, 3M, and other helmet headsets.

The 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. 

Our goal when designing the  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!  



  • 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.
