Earmor M11 ARC Helmet Rail Adapter Attachment Kit

The Earmor M11 is a mounting kit that allows the Earmor M31 and M32 active hearing protectors to be directly attached to ARC rail tactical helmets. This adapter kit replaces the original headband or helmet mount (as on the M31H/M32H models), providing a secure and clean installation.

The mount features a 90-degree swivel mechanism that allows the hearing protectors to be lifted up and away from the ears – for example, during a break or to facilitate communication. The folding mechanism also keeps the profile low, so the equipment does not get caught on structures.

Compatibility and intended use

The M11 is designed to be compatible with ARC rail systems, such as those found on Ops-Core FAST MT, ACH, and MICH helmets. Compatibility has been specifically ensured with the Earmor M31/M32 hearing protectors, but the design also allows the use of other similar models, if the design allows.

The adapters are delivered as a complete pair (left + right), so installation is complete without additional parts.
