To celebrate the frankenstinian creation of my first ever Gen 3 PVS-14 (canadian eh) I revisited one of my longest running gear frustrations.
A few years back I picked up a set of TCI Liberator II behind the head comms & earpro for a good deal. I was happy. Then I bought a baby's-first-Ops-Core. I expected them to work together. They didn't.
TCI had some less than ideal solutions. And after several months I pretty much gave up.
Having some proper NVGs and a reason to wear the helmet caused me to cycle back around. I wound up removing the side padding from the helmet, unscrewing the fitband and installing the liberators underneath the occ-dial. Now they actually stay on my ears, and the helmet actually stays on my head. They're about the farthest thing from QD, but that's okay by me.
