I have an opportunity to buy a new Burris Fullfield II Ballistic Plex E1 4-5-14X 42mm for $270. I know it's a great price, but I don't know much about the scope. The reviews are very good, but I was hoping someone out there who owns one can give me some feedback. I'm planning to put it on a yet-to-be-purchased rifle, but maybe a 257 Roberts.
