EARMOR M31H MOD3
For people wearing a helmet
The same active suppression as the M31, without the headband. The cups clip onto the ARC rails of your helmet so nothing presses underneath it.
A normal headband under a helmet is a well-known source of headaches: the band pushes against your skull, the helmet pushes back, and after an hour you just want the thing off. The H version hangs on arms that clip onto the side rails of your helmet and swing up when you don't need them.
Check which rails your helmet has. ARC (Ops-Core style) is the most common; separate adapters exist for M-Lok and Team Wendy EXFIL 3.0. Without a railed helmet this model is useless to you, so pick the regular M31 instead.
Who is this for?
- Airsofters with a FAST or ballistic helmet
- Instructors who train wearing a helmet
- Anyone bothered by a band under the helmet
