Nightforce ATACR 5-25x 56mm Rifle Scope - SEE WHAT YOU'VE BEEN MISSING. Chances are, you'll never forget your first look through the ED glass of our ATACR 5-25x56 F2. Nightforce can assure you that you've never seen an image through a riflescope as bright and impressive. Extensive elevation travel allows target engagements at distances previously considered "out of range," if you're willing to practice and if your rifle is up to it. Your riflescope certainly will be.
