Vortex Crossfire 2 MOA Green Dot Sight - Multi-Height Mount, 11 Brightness Settings - CF-GD2

The Vortex Crossfire CF-GD2 is a 1x reflex green dot sight built around a 2 MOA green dot reticle for fast, both-eyes-open target acquisition. The 21mm objective lens is fully multi-coated for clear, bright viewing, and the sight offers unlimited eye relief with a parallax-free design so the dot stays on target regardless of head position. Construction is nitrogen purged and rated waterproof, fogproof, and shockproof for use in demanding conditions. Windage and elevation adjust in 1 MOA increments across a 100 MOA range in each direction, giving plenty of room to zero. Power comes from a single CR2032 battery, with a rated battery life of 50,000 hours. The sight ships with a Multi-Height Mount System that includes a Lower 1/3 Co-Witness mount and a Low mount, letting it be set up to match different rifle or shotgun configurations. Brightness is controlled through 11 illumination settings, 9 for daylight use and 2 that are night-vision compatible. The unit measures 2.5 in in length and weighs 4.59 oz, and is finished in black.
