Does anyone know if you can fit this British Radio headset under a helmet. I'm doin a Modern Marine bash and i wanna put it under the BBI MARPAT helmet. I've been struggling, but i don't wanna screw up the radio or the fig's head.

I'm trying to fit this radio under any BBI helmet. I think it's the DML Evan British Sniper Headset.

It should fit, depending on the figure's head. I used the head from bbi's "Trident". On him though I used Elmers white glue. Just a little (about a pin head drop on all four sides) on the ear piece, to keep it in place--let it dry.
