Strike with the quickness and accuracy of a cobra. The Vortex Venom Red Dot Optic installs easily to give your AR, pistol or shotgun a big boost in accuracy and targeting speed. Put the dot on the spot, and that's where the hole will be. Shot after shot. In face, some of our customers have said that the Venom has maintained zero after 4,000 shots. And with up to 150 hours of battery life on high (and up to 30,000 on low), it's the fuss-free targeting solution your gun needs.
