Do you hunt? Shoot field target? Plink? Eliminate pesky garden varmints? This is the scope for you! What an incredible bargain. From the emerald coating on the lens to the illumination options, this scope really delivers the goods for any type of shooting discipline. 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.
