I bought a Fullfield II a year ago, and love it but for the fact that the rubber tip on the eyepiece fell off.. I glued it back myself, and its one of the finest I ever used. clear, bright, and accurate... when I move it 2 clicks it goes 2 clicks, etc. I have it on a 300 WSM, Mine has the ballistic - plex feature, and I have yet to use it in the field, but seems to be handy.
