The Cronus BTR Gen II 4.5-29x56mm Riflescope by Athlon Optics delivers high versatility and outstanding performance. It comes equipped with UHD Extra-Low Dispersion Glass, which considerably reduces the effects of chromatic aberration while simultaneously enhancing image quality with sharp, vibrant colors. This scope is equally well matched for precision rifle shooting and long-range hunting, and features an internal stainless-steel component turret design to produce highly audible and tactile clicks. In addition, the illuminated, etched-glass reticle is in the first focal plane that shrinks or grows when zoomed in or out, allowing for rapid target engagement at low power and precise holdover positions at high power.
