AK 107 assault rifle , like its analogues under the index 108 and 109, was designed by engineers Aleksandrov and Paranin, who are employees of the Izhmash enterprise. This unit belongs to the Kalashnikovs 100th series, the models differ among themselves only in the charges used. The main feature of the combat unit is the use of balanced automation.
Features
The use of special automation has significantly reduced the recoil and oscillation of weapons during firing. This especially affected the shots in bursts, providing better aiming and accuracy of hitting the target.
Such solutions were implemented on prototypes of AL, the development of which was carried out in the 60-70s of the last century. However, these specimens did not go into mass production due to the presence of such shortcomings as: severe pollution, low working life of a number of parts, and spontaneous opening of the receiver cover during firing.
Modernization
Automation of the same type was used in the gun AEK-971, which was developed at the Kovrov plant. The AK 107 assault rifle differs from this model in that a number of modernizing elements are included in the design. Among them: an additional gas piston, a rod with a counterweight, a synchronizing device (placed between the bolt part and the balancer). In addition, a number of minor improvements have been made, such as the modified fixation of the receiver cover of the receiver.
The upgraded AK 107 submachine gun received minor improvements over its counterparts using a wired automation. Externally, the guns are distinguished by the elongated dimensions of the gas piston and the casing, which aggregates with the barrel pad masking the balancer.
Balanced Automation
The AK 107 assault rifle, thanks to the system under consideration, is capable of absorbing part of the pulses during the return of the gun. This factor contains a complex of several influences. Among them:
- Impulse after firing, issued even with the shutter closed.
- Then the shutter kit is retracted and rests on the rear of the barrel box, which provokes another impulse.
- The final effect is due to the supply of an oppositely directed pulse when the shutter is moved to the far right position during the final reload cycle.
The recoil of a shot of AK 107/108/109 assault rifles is reduced due to the use of an effective muzzle compensator with a brake. The remaining pulse feeds have a more sophisticated blanking configuration. For this purpose, an automatic balancer is used with an additional analog, which is moved simultaneously with the shutter mechanism in the opposite direction. The weight of the balancing device and the bolt group is the same, as is the speed that is provided by the synchronizer, which is responsible for the opposite direction of the nodes with respect to each other.
AK 107 assault rifle: specifications, photo
Below is a photo of the weapon in question, as well as its main technical plan parameters:
- Caliber type (modifications 107/108/109) - 39/45/39 mm.
- The principle of operation is a rotary shutter and balanced automation.
- The trunk along the main length is 415 mm.
- Curb weight - 4.2 / 4.3 kg.
- Range of aimed firing - 1 km.
- Rate of fire (burst / single shots) - 120/40 volleys per minute.
- Ammunition launch speed - 900/750 meters per second.
- Magazine capacity - 30 rounds.
Comparative characteristics
AK 107 is an automatic machine that uses pulses of the balancing and gate assembly, which makes the total opposite flow equal to zero. Parts of the active group upon reaching the extreme upper position, due to their own movement, transmit the shock direction to the fixed elements of the gun, after which the impulse is transmitted to the arrow and the body. Colliding with each other, they cancel each other out.
When firing bursts from an AK 107 assault rifle, the weapon is exposed to recoil caused solely by a salvo. At the same time, there is a significant decrease in DTC, which increases the accuracy of shots by an order of magnitude, regardless of rate of fire. The movement of the moving elements of automation is reduced, compared with the classic variations of the Kalashnikov. This decision allowed to increase the rate of fire to 900 volleys per minute.
AK 107 assault rifle: description
The design of the gun consists of a pair of return springs. One of them is located between the shutter frame and the rear of the receiver. The second element is between the balancer and the shutter, which compresses the assembly during opening.
The trigger mechanism is identical to the basic counterparts used on AK. In addition, there is a function of firing bursts of three rounds. The fuse has not changed. It is only adjusted for the possibility of firing in short bursts. Accessories made of plastic in black and a folding side butt, as well as adjustable sighting devices are identical to the AKM-74 modification. Among the additional functionality: night or collimator sight, bayonet-knife, underbarrel grenade launcher.
The AK 107 Kalashnikov assault rifle is equipped with a reliable clamp for the sight and receiver cover. In the new modification, a change in the geometry of this node is observed. The sector sight is mounted on the front edge of the stem, while it is connected to the groove of the lining, providing additional fixation of the cover.
Update
Already in 2011, the Izhmash enterprise brought to the public a new sample - the AK 107 submachine gun, which is equipped with a Picatinny rail type rail. It makes it possible to mount various types of sights much faster and more conveniently. At the same time, the standard rear sight of the U-shaped configuration is replaced by a model with adjustable diopter. The designers themselves placed the assembly on the rear surface of the trunk box lid. In addition, a four-row box-shaped magazine was developed with a capacity of 60 charges.
Disassembly
Below is a disassembled photo of the gun under consideration with explanations.
- Receiver with a barrel, trigger, butt and sighting mechanism.
- Shutter part.
- Shutter frame with gas type piston.
- Counterweight.
- The mechanism of the return type.
- Gas pipe and barrel plate.
- The receiver cover with an eye.
- Clip on 60 charges.
Automatic fire is denoted by the abbreviation "AB", a line for three rounds - "3", single shooting - "OD".
Modifications
AK 107 assault rifle, the characteristics of which are discussed above, as well as its analogues under numbers 108 and 109, differ only in the type of cartridge used. Special automation works by running a gas engine with increased movement of the element and the balancer, which is equipped with an individual gas piston moving in the opposite direction from the main element. The balancer is synchronized with the shutter frame via a gear, which is in vertical aggregation with it. A rebound in the moving parts of the gun is provided by a special part. The trunk channel is closed according to the principle of identical constipation in the AK-74 modification.
Total
In the "hundredth" series of AK developers from Izhevsk embodied in the new models (AK 107/108/109) all the best from old models and innovative solutions. Modernization allowed to increase accuracy when shooting, accuracy hit, and also reduce the impact of recoil. The result was an automatic weapon, which began to be in demand not only in the domestic army, but also among official foreign partners.
