What is the Best Example of Advanced Scope Technology? The Nightforce BEAST. The BEAST is a cut-no-corners scope born from the military’s need to assist snipers in identifying targets at ever-increasing ranges. The BEAST features a DigIllum first focal plane reticle, XtremeSpeed adjustments, i4F intelligent four-function elevation control, ZeroStop, 360° brake, over 90% true-to-eye light transmission, and an optical prescription designed through the collaboration of US and German engineers.
