The helmet adapters from FMA are used to conveniently attach the Peltor Headsets Comtac I and II to helmets. For this the adapter has two clips on each side into which the headset mounting pins can be clicked. In combination with the rail adapters, the ear cups can now be attached to the Picatinny rails of the helmet. The advantage of this adapter is that the headset can be folded away from the ear when not in use, thus allowing noises and air to reach the ear. This allows that at the same time, that the protection as well as and the possibility of communication are possible with a quick movement.
