This is as good as it gets when it comes to optics. This high-quality scope is bright and tough. The True Strength platform ensures that this scope won't break if you mount it on a magnum-powered spring-piston air rifle. Ideal for hunting, hunter field target, plinking, pest elimination and more. Can also be mounted on any firearm or airsoft gun with a Weaver rail. This UTG scope has an etched-glass reticle, which is superior to a wire reticle because it's etched by a laser and is much more precise. That lets you get even more accuracy from your gun. Another way that etched-glass reticles are superior to wire reticles is when they're illuminated. The etched ones show the illumination only on the reticle. It looks like the reticle is floating. Wire reticles often have a reflection of the illumination in the objective lens, which can be distracting when shooting.
