The domestic carbine "Saiga MK-107" was developed by Izhevsk gunsmiths. It is made in the form of civil self-loading modification of the AK-108 assault rifle. The weapon was created and released in 1997-1998. based on the hundredth version of the famous "Kalashnikov". The main difference of the model was the use of balanced automation. It was made in the image of AL-7 (Abakan). The main purpose of weapons: sports, hunting for game, protection of possessions.
Concept and dynamics
The main device of the Saiga MK-107 carbine includes balanced automation. This design implies the neutralization of the impulse of heavy mobile weapons elements by equipping it with a balancer (anti-mass). The device moves opposite to the direction of the shutter block, minimizing its recoil and back impulses, which affect the stability of the rifle while firing. At the same time, dynamics and aiming are improved when working on moving targets from an uncomfortable position.
Thanks to the introduction of the balancing design, the recoil, the vibration of the gun and the instability of the trunk portion are reduced, which is particularly appropriate for high-speed shooting. In mass production the carbine "Saiga MK-107" with the balanced automatics came out in 2016. The starting modification is proposed in the "Remington-223" caliber.
The weapon in question is equipped with an automatic system with a pair of pistons serving for exhaust gas removal. They are mounted one against the other, they enter the common cylinder, which is placed in the middle above the barrel. The rear gas piston interacts with the gate frame through the stem. After triggering, it comes back, and the weapon is recharged.
The front element is connected to an elongated balance bar located above the gas cylinder and the gate portion. It moves along the "forward-backward" trajectory. Synchronous interaction between the rocker and the frame provides two gears placed in a special compartment, which remains immobile during shooting. Also these elements interact with the holes in the rod, piston and balance bar.
Carbine "Saiga MK-107": the device
In case of partial disassembly, the carriage with the gears is disconnected from the complete set by the whole unit. It includes a balancer with a return spring. The last element is in a barrel box manufactured by stamping. From the axis of the weapon the mechanism is shifted to the left.
Closing of the barrel is performed according to the standard principle peculiar to AK automatic machines. Provided are rotary type gates with a pair of fighting stops. The cocking levers are made on both sides of the bolt frame, move when firing with it in a bundle. The trunking of the barrel box is equipped with a special guide element for the installation of additional optics.
The fuse in the form of a transverse button is located above the trigger box. In addition, the design of the Saiga MK-107 carbine includes a latching delay, a magazine shaft, which accelerates recharging. The clip itself in most cases is taken from rifles line AR-15 or M-16. The non-folding telescopic butt is adjustable in length.
The domestic self-loading carbine "Saiga MK-107" has the following technical parameters:
- serial caliber - the 223rd "Remington" (5.56x45);
- the total length of the weapon is 98 centimeters;
- a similar figure with a deployed butt - 1.03 meters;
- the trunk in length is 41.5 centimeters;
- weight - four and a half kilograms;
- the capacity of the store is ten charges.
With all the advantages of the carbine in question, it has one significant drawback - it is a significant mass, which is 900 grams higher than the standard "Saiga".
History of creation
Since the AK-107/108 models of the 5,45 / 39 and 5,56 / 45 calibers did not find wide consumption in the market for various reasons, Izhevsk gunsmakers decided to make a cunning marketing move. They developed and released a civilian modification called "Saiga MK-107".
These weapons are aimed at the target destination for athletes engaged in practical shooting. The background of the idea was the creation of a sports carbine, focused on IPS. At the same time, it should be cheaper and more accurate than analogues. The undeniable advantage of the new weapon was the lack of trunk shock during the execution of doublets, since there is a special mechanism that corrects the movable elements of the weapon in the extreme stops.
Due to this solution, the bolt frame beats are canceled by compensating pulses of the balancing bay, which reduces the throwing during shooting. In comparison with the classical modifications, the version with balanced automation has a consistency almost two times higher.
Presumably, the only possible semi-automatic mode for this civilian carbine prevents the jumping of weapons from the hands of an inexperienced shooter. The MK-107 is equipped with a telescopic butt, an ergonomic handle with a pistol type, and a set of Pikatini slats, which enable the use of various additional attachments. These include:
- optical sights;
- handles of a different type;
- night-vision devices.
There are all prerequisites for a self-loading carbine "Saiga MK Sp. 107 "became a sensation in the arms market in its category. This is due to the excellent design, unpretentiousness in maintenance and great accuracy, which provides a balanced automation. And the popularity of the weapons in question, which can be used for self-defense and hunting, will not take long to wait both in Russia and abroad.
