The Vortex Crossfire Red Dot Sight provides no-nonsense performance and a quick, simple point of aim. The Crossfire red dot has a 2 MOA dot reticle that offers quick target acquisition at close range but offers accurate aim at longer distances too. Fully multi-coated lenses increase light transmission for a bright image, while the parallax-free design ensures consistent accuracy and aim. Plus, the Vortex Crossfire is built tough with a hard-anodized finish, as well as waterproof O-ring seals to protect against debris and moisture. With 11 levels of brightness, the Vortex Crossfire Red Dot Sight offers a simple, accurate aim for nearly any application.
