no, the gameseeker isn't the Burris fullfield. I think it is either the lightseeker or the whitetail model that is the relabeled Burris. Regardless the Gameseeker is an excellent scope for the money. I had one in the 4-12X40 for several years on a 7mag and it worked very good. It always held zero, it never fogged and it was fairly clear. I noticed that if I had mine on 12 power and was looking at my target out 400 yards or farther it started to get a little blurry. But for the price a very good scope.
