When the situation demands fast shooting. . .and a big scope with a narrow field of view won't cut it, the StrikeFire red dot riflescope lets you shoot quickly with both eyes open! With unlimited field of view and eye relief—nothing gets you on target faster than this tough, shockproof and waterproof red dot scope.
The Strikefire's sophisticated circuitry shuts the unit down after six hours. Average CR2 battery life depends on the dot intensity setting, color and mode being used. Typical battery life in normal mode of operation: 200 hours (maximum brightness), 5600 hours (minimum brightness). Typical battery life in night vision mode: 6800 hours (maximum brightness), 8000 hours (minimum brightness).
Note:If you have a carry handle version of the AR15, you will usually need the lower Low Mount model. You will also need a carry handle mounting rail.
