Keep a bead on your prey and strike fast with the Mantis 4-12x40 AO scope. The mid-size 40mm objective lens allows shooters a wide field of view without being too bulky. Large and in charge at 40mm, this Adjustable Objective scope allows shooters to magnify their chosen target 4-12x. Featuring mil-dot reticles for easy holdover/under for shooting at variable distances and windage. Like every Mantis, the 4-12x40 is built to hold up to the recoil of high powered springers, and essentially weatherproof (resistant to fogging, and water).Specifications and Features:Mantis 4-12x40mm AO Mil-Dot Scope FeaturesRifle scopeVariable 4-12x magnification40mm objective lens - adjustable objectiveMil-Dot reticle1" tubeSnag-free turrets1/4 MOA (1/4" click value @ 100 yds)Parallax adjustment 5 yards to infinity18 oz.13.5" lengthMulti-coated lensNitrogen filledFogproofWaterproofShockproofHeavy duty aluminum constructionBlack matte finishPlease note Mounting rings are NOT included with this scope.
