Clear, bright, and tough, the Vortex Crossfire II line is built to exceed the performance standards of similarly priced riflescopes. Long eye relief, a fast-focus eyepiece, fully coated lenses, and resettable MOA turrets are hallmarks of the series. Crafted of premium, aircraft-grade aluminum, the waterproof one-piece tube delivers both optimum visual performance and strength. O-rings prevent moisture, dust, and debris from getting inside the tube. All Vortex Crossfire II riflescopes are backed by Vortex's VIP unlimited lifetime warranty.
