Burris 3.5-10x50mm Fullfield II Ballistic Plex Rifle Scope - Matte Black Finish Product Info Burris 3.5-10x50mm Fullfield II Ballistic Plex Reticle Matte Black Rifle Scope 200172 have 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 3.5x - 10x RifleScope 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 Full Field II 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 Ballistic Plex reticle has a lower vertical crosshair with small ballistic lines that automatically compensate for bullet drop from 100 to 500 yards for many common cartridges. The Burris Fullfield II 3.5x-10x 50mm Rifle-Scope is lighter, better sealed, and has a relocated adjustment system compared to the original Fullfield.
