The large 56mm objective indicates tremendous light transmission qualities that will yield an amazingly bright sight picture, right up until the last light of twilight.For long-range target acquisition, the not-so-insignificant bump up in power to 12x can be the deciding factor when attempting those longer shots that most shooters will have to pass on. Still, this scope is not lost when attempting close-range shots. You can simply and easily dial down the power to 3x for a brighter and wider field of view. This construction of this scope is ergonomic, durable and precise. Low profile target turrets and a generous eye-box deliver quick and accurate sight and target acquisition. 1/4 MOA precision adjustments help you to fine tune your shot placement and for those long-range shot the 30mm main tube affords this scope a substantial increase of maximum possible adjustments. Getting your reticle tack-sharp is a breeze thanks to the robust fast focus eyepiece.
