Viridian has a new line of affordable high-quality optics which are sure to help you get on target and stay on target. The GDO 22 is a 1x magnification optic that’s an ideal addition to your rifle, pistol caliber carbine, or shotgun. With a 3 MOA green dot reticle, you can quickly and easily acquire your target. Included are 11 brightness settings: 10 for use in daylight, and 1 night vision mode that allows you to use the optic in conjunction with night vision setups. Powered by a single CR2032 battery, you can expect around 30,000 hours of battery life on the medium brightness setting. The GDO 22 is made from high quality aluminum alloy which is durable, but also very lightweight. This optic fits any MIL-STD 1913 Picatinny rail and comes with two mounts: one low mount, one high.
