- description
There are two rail standards and two common cup patterns, which means four adapters. This is the combination for a helmet with M-LOK side rails and a Peltor headset — the pairing that leaves people convinced nothing is made for their setup.
Unusually, Earmor's own distribution lists this one as fitting both Peltor hearing protection and Earmor M31 and M32 cups, which makes it the most flexible of the four if you run mixed kit.
The mechanism is a rotary panel: twist the muffs 90 degrees when they are not in use and they are clear. A steel guide handles the locating, and the body is polymer.
Choosing between the four comes down to two physical checks. Look at the helmet rail, look at the boss on the earcup, and buy the kit that matches both.

Frequently asked questions
Which of the four adapters do I need? ARC rail with Earmor cups is the M11. ARC with Peltor is the M11 Peltor. M-LOK with Earmor is the M13. M-LOK with Peltor is this one — which also covers Earmor cups.
Why is the part code written oddly? Earmor's distribution publishes it with the brand name inside the part number. We store codes exactly as published so the stock feed matches, even when the formatting is untidy.
Will Comtac III cups fit? They use the Peltor interface, so the yoke is right. Always match the physical boss on your own cups rather than the model name.
Is this really more compatible than the plain M13? On published compatibility, yes — this is the only one of the four listed for both cup patterns. That is Earmor's claim rather than ours.
