I was looking at a 2004 wgp with an eye sensor the guy said it was easily adjastable from the outside of the gun i was wondering if this is a good feature to look for in an autococker or it really doesnt do much

Ya, get an eye. It helps a lot and the best eye out there is in the eblade. I just love it. Its got all the goodies in it/

Planet Eclipse released a new and improved eye with their zero b board for the e1.
