Aimpoint is one of the most trusted names in the optics system and their Aimpoint Comp M4 is one of their most saleable products. It has one of the longest battery lives among contemporaries in the market. The Aimpoint Comp M4 is available for a price of $700 in the market, making it impossible for everyone to get their hands on this fine product. This is not a problem for users who can’t afford it as Aimpoint is known to manufacture similar products of the same quality in a lower price range as well. The reason why it is priced so high is because of its ability to withstand impact, dust, dirt, mud, extreme cold and hot temperatures as well as its ability to function in deep water.
It has a sealed reflex sight which has a 2 MOA (Minutes of Angle) doubt that on its setting to lower parameters can be pretty precise art and over 100 meters. With increasing the brightness it becomes larger to the naked eye than 2 MOA and also creates a nice big ring where the tube meets the glass, which is unnoticeable until you are actually using it. It is more noticeable on focused groups. There are also 7 brightness settings for Night Vision and 9 levels of brightness for daylight out of which the “Extra Bright” turns it into a 40mm red light in your face.
Once you get the sealed covers off the elevation and windage, the sighting is pretty easy. The half an inch at 100 meter adjustment is covered with anodized aluminium and full gaskets so that they are easy to take off with or without gloves and are strong enough to prevent them from winding themselves off. You do not have to worry about eye relief or parallax because if the red dot is placed on a spot, then it will maintain that line of shot when the trigger is pulled. The life expectancy per AA battery is about eight years and the battery compartment is also fully anodized with a gasket.
Aimpoint uses their QRP2 mount, it is a quick release mount which is not a lever operated release but a screw down mount with a ratcheting knob. When the mount is tightened onto a rail and will click when it reaches a significant resistance to prevent over tightening or stripping the mount. In all, it is a compact, reliable and rugged optical system which is value for money.
