When situations demand split-second target acquisition and maximum field of view, mount up the StrikeFire II and shoot-both eyes open. Feature-rich, versatile and reliable, the StrikeFire II is a great choice for hunters who want a quality red dot sight, but don't want to break the bank. Sleek rear-facing controls allow for easy adjustment of ten dot intensity levels-lowest two settings are night-vision compatible. The 30mm aluminum alloy chassis provides extra-high recoil rating and is waterproof and fogproof. Strike fast! Mfg: Vortex Optics
