The Aimpoint CompM5 is a high performance red dot sight developed for military and law enforcement applications. Used as designed, gain lightning fast target acquisition and greater situational awareness by shooting with both eyes open. With an extremely robust housing design, expect the same ruggedness you have come to rely on from the CompM4 sight with less weight. Advanced optical lenses provide excellent light transmission and allow for unlimited eye relief. The CompM5 is perfectly matched with Aimpoint 3XMag-1 and 6XMag-1 magnifiers, as well as all generations of night vision devices.
