When your target is the addition of a new optic, check out the Vortex Crossfire II Scope. It's the clear choice from the moment you shoulder your rifle and stare down the generous eyebox and dial the fast focus eyepiece to keep the Dead-Hold BDC reticle sharp, clear and on-target. Fully multi-coated optics allow optimal light transmission so you can see what you need to in less than ideal conditions. The adjustable-objective front lens provides maximum image sharpness and parallax removal while the capped reset turrets helps prevent accidental changes to your settings once you focus and reset to zero. The Vortex Crossfire II is built to last starting with a single-piece 1 inch diameter tube made of aircraft grade aluminum with a hard-anodized, low-glare matte finish. The nitrogen gas purging and O-ring seals prevent moisture dust and debris from entering the scope to keep it fogproof, waterproof and shockproof. Mount one on your favorite firearm and you'll see there's no compromise and no comparison.
