Hey All, I'm working on a pair of Afterlife Goggles for my son. He's 16 and we are both huge gbfans! I've identified quite a few parts on the goggles already but I'm having trouble with one part in particular. The silver piece on the lens plate between the lenses.

As soon as my frame gets here, I will start a thread documenting the build and all the parts used. Hopefully someone here can help with this part. Thanks in advance!
