Vortexvortex Crossfire Ii 3-9X40 Rifle Scope, V-Brite Reticle Cf2-31025

The scope was purchased to replace a Walther, used for pest control with a CO2 rifle on private property, my typical working distance is from 15-80mtr. This new Crossfire ii has not been fitted and zeroed yet (purchased rings won't fit the rail), so I am reviewing the general usability and feel, whilst highlighting limitations such as minimum working distance, which is fine for live round rifles, but is more than required by CO2 or air rifles.This scope feels sturdy, The reticle adjustment works to get a crisp view of the reticle and it's illuminated red dot at the reticle centre (not projected to target), this will be welcome as light levels fall, although it is a little less bright than I would have hoped.Elevation & windage adjusters have a light/subtle touch without loud clicks. The image is bright and sharp at distances over 100mtr but lacking an adjustable objective lens or parallax adjustment leads to greater blurring as subject range gets closer, or when using higher magnifications; it may become more usable at close distances by using lowest magnification(3x), although this could lead to eye straining.A similar scope with parallax adjustment would be considerably more expensive, Scopes can be adjusted by service centres to bring the minimum focus nearer "Re-Parallaxing" (probably a turn or two of the objective lens). I'll consider this but it may invalidate warranty, in which case I will return the item unused.This review will be updated after checking if it can be adjusted to bring it within the working range of a CO2 rifle and after test firing.April 2021- Still works well, helps to achieve tight groups and holds it's settings. Focus was brought closer by adjusting the objective lens with a suitable tool.
