Burris took the Fullfield II 200330 riflescopes and gave them a sleek new profile with upgraded windage/elevation knobs, a new integrated power ring and eyepiece that will now accept flip-up lens caps. The Ballistic Plex E1 etched reticle is another Burris innovation that provides a simple, uncluttered method for determining for trajectory and wind compensation. Internally the features are precision ground lenses, index matched lenses with HiLume Storm multi-coating; double internal springs and positive steel-on-steel adjustments for repeatable accuracy.
