The Vortex Viper BDC scope packs a lot of unadvertised features into a great package. The turrets are resetable, meaning once you are dialed in you can "zero" them and adjust as needed for windage, elevation on long range shots. The BDC reticla is part mil-dot / part MOA and has meaningful windage marks and range marks that work out pretty well regardless of caliber. The clarity is pretty good, my only complaint was the vertical crosshair is just of off center on the etched glass reticle. But the clicks seem precise. The scope is only been through one range session but the logic behind the layout is sound and I look forward to more evaluations.
Pros: Features, Clarity.
Cons: Etched reticle slightly off center for the verticle line.
