The internals are the same as an EyeClops so... that's probably pretty empty, yes. What gives it that huge frontal area are the IR LEDs, otherwise if you slim it down to the camera and screen, there's not much (considering the batteries are external).
Actually, I was considering putting the internals of an EyeClops (so the same as that) into a PVS-14 dummy. That wouldn't be really expensive (EyeClops can be found at ~40$ and the dummy at 32$ shipped). That wouldn't be a real NVG, but could still be some use and would be better than an empty dummy.
And... I wouldn't have the guts to try that with a real NVG, even if it's a 150$ Gen1^^
