Too much of my 6' 2" height is in my back. Senior Gunner mount too small for me, the sight reticle would have probably taken the top of my head off. That day in training while they hook up all them cables to the Chaparral to monitor your performance tracking a remote controlled airplane: I slithered down now sitting on my lower back...discovered that I do not make a good Senior Gunner anyway. They made me driver and I was a great one. I was ONE with that GM M730 man. Blew the supercharger quill shaft one day and got my whole unit out of being messed with for a whole week of field exercise at Hunter Liggett. Fell asleep once driving down side of mountain and got woke up by a low hanging tree branch hitting my steel pot.Remember warming up at the MPU exhaust?
