KSO 9 Krechet carbine, rifled gun

Self-loading carbine KSO-9 “Krechet” is produced in the Zlatoust machine-building plant, based on its design submachine gun PP-91 “KEDR” (Design Eugene Dragunov).

Description of the carbine KSO 9 Krechet

Self-loading carbine blowback, receiver, pistol grip and USM taken from a submachine gun “CEDAR”.

Left the same and the type of ammunition – pistol cartridge “Luger” 9×19.

  • So that he fell into the category of civilian weapons, back to the receiver attached pipe (threaded joint) on which is mounted a sliding butt. Increased barrel length (360 mm) and for entry into the standard on the muzzle arranged openwork brake-compensator.
  • Magazine size reduced from 30 to 10 rounds, but if you want you can put the combat option. Changed USM left one firing mode – single.

The design of the carbine is only used metal and plastic. The whole “kit” taken from the Israeli arms company CAA Industries.

  • Handguard attaches to the barrel with clamps and is actually only the trim on the trunk not bearing structural loads. It is square, it contains three straps weaver for the canopy handle, tactical flashlights and other items.
  • Cover the receiver received reinforcement in the form of a bracket weaver high bracket. There is an external sights – folding rear sight and front sight.

In the end, the upgrade, the designers instead of PP “CEDAR” was something resembling the American assault rifle M4.

Advantages and disadvantages

The carbine looks like it was pulled from the movie “starship troopers” or virtual reality RPG like Mass Effect. Someone that can warm the soul, but also the “cool” type and other Ponte, dignity KSO-9 “Krechet” it ends.

  • The main and fatal flaw is the attempt to make the carbine pistol cartridge. Can’t the nine-millimeter bullet with a rounded end to have the same ballistic characteristics of the rifle. This is contrary to the laws of physics, so “Merlin” is to lose all the small indicators, accuracy, precision and stopping power of any carbine with a rifle bullet. For example, “the Saiga of MK” in the performance of the 03, even though its shorter (336 mm) barrel.
  • For example: the rifle ORSIS-120 when shooting at a distance of 100 meters gives the deviation from the aiming point is not more than 2.9 cm, which is equal to 1 MOA and that is why he gets into the standard sniper rifles. The “Cedar” dispersion at the same distance of 15 cm, which is acceptable for a machine gun but for a hunting rifle is unacceptable.
  • The carbine is all rough, angular, many protrusions. For hunting – this is simply unacceptable. Handguard with three straps weaver – separate “song”. This is only for fans of the “Zombie Apocalypse” may seem like a very useful device. For the hunter is more important than the convenience of grip and durability, and massive panel hanging on the trunk, has no practical value. By the way, the American assault rifle M4, which is so similar to “Merlin”, has the best ergonomics.
  • The knob is on the left. This is a great idea for a submachine gun, because if the right hand grasped the handle and finger on the trigger after cocking, you can immediately open fire. The carbine KSO 9 Krechet, which is positioned as hunting, this feature is not needed, it is rather dangerous.
  • Separately want to mention the traditional Russian arms tight to move all of the parts. The fuse box is shifted with great effort, compounded by its small size and angularity. By the way, the bolt handle is also small and angular, to operate it extremely uncomfortable.
  • For a partial disassembly of the rifle required tools that adds convenience in its use.

With all these disadvantages, its price exceeds 50 thousand rubles. Now compare “CEDAR” and “the Huntsman” (by the way, they have the same weight – 3.2 kg), standing the same and it will become clear how justified the purchase of the product from Chrysostom.

It remains to Express a dissenting opinion, that neither that, nor another it is better not to use. Hunting will produce wounded, and for the defense would’ve been better KEDR unchanged.
