The Kashtan 1P78 Military Collimating Dual Black/Green Rangefinding Reticle Tactical Combat AK Rifle Scope is exclusively exported by Kalinka Optics. This is the newest collimator scope made for the Kalashnikov. Proof of that is in where you will find it, on the rifles of elite units in Russia's Ministry of Internal Affairs (MVD): police, Spetznaz Special Forces, OMON, etc. Such units aren't going to use anything but the best. The Kashatan and the Obzor are the leading edge of collimating technology from the NPZ factory. The scope reticle is graduated for all AK's using 5.45x39 ammo. The upper chevron is marked for 400 m, the dot is for 500 m, the upper chevrons work for 600 and 700 m. It not only fills the role of the traditional CQB short range/fast acquisition sight, but also has unique features designed specifically for longer range combat shooting. The reticle and scope ability is geared for a single shot kill on an AK-74N at 400-700 meters in day to heavy dusk conditions. It's fully coated prismatic lens system provides a remarkable, high contrast, wide angle field of view allowing for fast acquisition of moving and spaced targets. The advanced battery-free, illuminated green German post reticle allows the Kashtan to be used in extreme dusk conditions. You have an unlimited field of view and maximum ability to register incoming targets. The precision dot system combined with the striking field of view produced by the high quality lens system provides far superior accuracy at distances exceeding those capable with iron sights. The scope has very accurate windage and elevation adjustments in small increments (every turret' click moves POI by 3 cm at 100 m). The special protective lens coatings protect the scope from scratching and fouling in the extreme battlefield conditions where it was designed to operate. A light-dividing mechanical and coating system produces exceptional dual visualization of the target and reticle at the same time so you see both in high resolution for better targeting. Notice the extreme temperature rating on this scope, you'll quit before it will. It comes with a heavy duty carry case, screwdriver and safe bag. A definite BEST CHOICE! Compare the Kashtan to Trijicon scopes and you'll find the performance equal or better at a lower price.
