This Leapers UTG AccuShot scope is a hunter's dream come true. While the red-green reticle has become commonplace, Leapers' has jumped ahead of the competition with their unique 36-color reticle. That single feature will deliver better results for hunters, who often track their quarry in poor lighting conditions. If the sun doesn't always shine or the moon isn't always full when you're hunting, then you need this scope! Never again will you have to say "I don't know if I'm on target" because you can't see your reticle. This fine scope has a 30mm tube and superior optics, which will surprise you with the amount of light it transmits. Put this on any gun...firearm, air gun or airsoft rifle...and commence to shootin'.
