This system presents an unobstructed field of view, in 1x power which allows for extremely comfortable, "both eyes open" shooting. On average, most users will see a 1.5 times faster target acquisition and a 50% smaller shot group at 100 meters, in comparison to the iron sights. It is designed for engaging fast moving targets and targets appearing for a short period of time in close quarters and urban combat situations in various light conditions. It provides clear targeting from 104 lx to 10-2 lx (daylight, twilight and moonlight), one- or two-eye targeting, is very effective when shooting from moving vehicles, and allows for perfect kill shots on fast-moving, small and spontaneously appearing targets. You get a choice of four aiming marks - single dot, open T, reversed chevron or reversed chevron with dot on top. All these can be selected by the simple push of a button, as opposed to having a dial them in. The ON/OFF is a rotary lever and the rheostat, a rocker switch, are all located on the bottom of right side of the body. At the rear top and left are the adjuster turrets. There's even a tool that allows you to re-zero the turrets if you run out of adjustment. It is a tough, well-built Red Dot with superior features at a fraction of the cost of other similar scopes. It has also been seen in service over the last several years in Caucasus, and is a battle tested design which has proven worthy of the Russian military tradition of reliability, form, and function. It has elevation and windage adjustments, ballistic correction limits from 100-700m, is lightweight, shockproof, has a sealed body, and is for use in severe conditions. The 16-level digital brightness adjustment is an added plus. It has been proven that the Kobra tremendously improves aiming effectiveness, especially at nighttime, resulting in more target hits.
