The improved Kashtan 1P78 Military Collimating Dual Black/Green German Post Reticle Tactical Combat Rifle Scope now known as Kashtan-2 is exclusively exported by Kalinka Optics. This is the newest collimator scope made for the Kalashnikov. It's technically the same to Kashtan 1P78 but developed to 21st century requirements. 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 was developed from well known German Post to more useful BDC/rangefinding one (see the reticle description on the picture). 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 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. You have an unlimited field of view and maximum ability to register incoming targets. 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-2 to Trijicon scopes and you'll find the performance equal or better at a lower price.
