I have a buddy that has just offered me a used (app. 70-80 rounds through it) an FN Patrol .308 with a Zeiss scope. He is unsure of which scope/magnification but is confident it is a Zeiss. He said he would sale the entire package for 650-700 bucks. How do they match up against the popular remmy's or other sharpshooters? I need to know by lunch tomorrow if I want it, so any information would be appreciated. I don't know much about the FN line of fire arms.
