Burris Optics 200161 Fullfield II Series 3 - 9x - 40mm Riflescope has a one-piece main tube and eyepiece, Burris envied steel-on-steel adjustment system and HiLume multi-coatings on every single air to glass lens surface. The Burris FullField-II Scope is even more forgiving for eye position, is a little shorter and a good bit lighter. The magnification ring and eyepiece have been made into one solid unit requiring only two seals rather than three.
To change magnification, simply turn the entire eyepiece. Burris Fullfield 2 Scope eliminated most of the potential leak paths in the eyepiece/power ring area and sealed the remainder with special quad seals instead of O-rings. The adjustment system has been moved to improve mounting options and the European-style adjustable eyepiece requires no locking mechanism. The Burris Fullfield-2 Riflescope is lighter, better sealed and has a relocated adjustment system compared to the original Burris Fullfield.
