Micro-Fire™ by Messer Optics™ The Micro-Fire is the smallest and lightest red dot on the market. Mounts very low, and weighs a mere 1.6 ounces. And it has repeatedly proven it’s toughness on the slides of high power semi-autos, on slug guns, on shotguns and on high power rifles.The Micro-Fire housing is made of aircraft grade metal for strength and durability. Its lenses are precision ground and polished to exacting geometries to virtually eliminate parallax and to provide a very clear crisp sight picture. It is fully windage and elevation adjustable and lockable. It features both an on/off switch and a light sensor that automatically adjusts the dot’s brightness to the available light. The included plastic hood covers the light sensor and puts the unit in sleep mode when the on/off switch is set to “on.” Mirco-Fire is powered by a lithium CR2032 battery, which is commonly available and long lasting because of the highly efficient electronics and the battery-saver mode. A battery can last as long as five years. For more scopes and mounts visit Messer Optics
