The Vortex Crossfire II 2-7x32 Crossbow Scope is packed with features, many of which are specific to crossbow applications. These features include a 30mm tube for maximum internal adjustment, cap turrets, and dual illumination with intensity controls. It's also fogproof, waterproof, and shockproof. Looking inside the Bow and Crossbow Sights, the XBR-2 reticle will flash either red or green. The system was designed for a 40-yard zero, but it will provide holdovers between 20 and 100 yards. Additionally, the Vortex Optics crossbow scope can be tuned to fit crossbows with different feet-per-second ratings. You can fine tune the reticle with the magnification to match the desired FPS. On top of the high-end features, the Crossfire scope kit includes everything you need to use it. This includes scope caps, rings, a battery, and more. By the numbers, the scope is 9.5 inches in length and weighs 14 ounces. Gear up for the next crossbow season with the Vortex Crossfire II 2-7x32 scope!
