Clearer. Tougher. Brighter. The popular Vortex Crossfire riflescopes are completely redesigned and built to exceed the performance standards of similarly-priced riflescopes. Longer eye relief, a fast-focus eyepiece, fully multi-coated lenses and improved resettable MOA turrets ensure optimal performance in the field. The hard anodized one-piece aircraft-grade aluminum tube is nitrogen purged and O-ring sealed for a lifetime of waterproof/fogproof performance.
