Made in Ukraine - promising "Equalizer"
Back in Soviet times, it was decided to abandon 7.62 mm ammunition to ensure automatic firing. This was due to the fact that the use of a 7.62 mm cartridge caused greater recoil, which negatively affected the accuracy of fire, in addition, the recoil momentum constantly knocked down the sight, and the shooter became very tired, which reduced the accuracy of the fire. There were attempts to remove negative characteristics using various technical solutions. But these attempts were quite ineffective. Therefore, in order to eliminate the shortcomings, we went the simplest way - we reduced the used cartridge caliber to 5.45 mm. Compared with the use of 7.62 caliber ammunition, the striking characteristics have become much worse. To increase the striking characteristics, they began to use in weapons fixed queues - that is, they began to take not by “quality”, but by quantity. The implementation of technical innovations to compensate for recoil using a caliber of 7.62 mm or improving the characteristics of a defeat when using a caliber of 5.45 mm was characterized by a complication of the design of automatic weapons, which ultimately reduced reliability and increased the cost of manufacturing weapons. From this situation, a logical decision arises on the creation of weapons that would be able to produce automatic firing of 7.62 mm ammunition and would not have the above negative consequences that arise when firing 7.62 mm ammunition.
Project "Equalizer"
Ukrainian promising machine operates due to the useful impact of the short stroke of the barrel. Before the shot, the barrel with the bolt and bolt carrier looks like a single knot. In firing, a “single knot” under the influence of an acquired recoil pulse begins to move backward. Having passed the path in 10 mm, the barrel and bolt stop and pass some distance forward, where they completely stop, being in a kind of intermediate position. The shutter frame, separated, continues to roll back, at this time, the shutter finger, touching, slides the groove of the copier type on the bolt carrier. The groove, in turn, causes the shutter to rotate, which ultimately leads to unlocking the latter. For 0.5 cm before the end of the movement of the frame of the gate, the hook of the bolt carrier interacts with the protrusion of the barrel, which is in an intermediate state and the last 5 mm they pass in one bundle. The movable parts of the machine have enough mass to reduce the impact force when you roll back to the back position. With the return of the mobile unit forward, the barrel again becomes in an intermediate state, the bolt frame pushes the bolt itself, and he, in turn, sends the next ammunition to the chamber. The bolt carrier continues to move forward, the reverse rotational movement of the bolt occurs due to the interaction of the bolt pin and the slot of the frame. It leads to the locking of the barrel. At the end of the movement all the moving parts of the machine again form the form of a single node. The details move together forward, and at this time the trigger interacts with the drummer, and a shot is made. The recoil from the shot prevents the movement of a “single knot” forward, which reduces the “rolling effect” - the impact of moving parts when returning to the most forward position. In order to give a higher reliability and increase the rate of fire, the weapon was supplied with a gas accelerator - the removal of a certain amount of gas from the barrel channel. Powder gases have an effect on the piston rod, and he, in turn, gives impetus to the frame of the shutter. The booster has a faucet that can be opened or closed by the user of the weapon at its discretion. USM made a hammer type. You can shoot as single shots and bursts. The fire interpreter plays an additional role as a safety device. In addition, the promising automatic machine is provided with a shutter lag.
Key Features:
- layout of the machine - bullpup;
- The total weight of the machine - 3.8 kilogram;
- length - 78.2 centimeter;
- barrel - 50 centimeters.
- the weight of the "Equalizer" with the equipped magazine, mounted with a bayonet, unloaded grenade launcher - 5,8 kilogram.
Proceeding from such a scheme for creating an automaton, one can fairly confidently assume that:
- the use of the “single knot” scheme and its movement reduce the possibility of a shift of the gunner’s shoulder when making a shot;
- 2-x multiple use of the weight of the barrel will greatly reduce the impact when shooting;
- hitting the cartridge capsule before the arrival of the “single knot” system will effectively reduce the possibility of a machine gun nod when firing in bursts;
- provision of an automaton with a gas accelerator will increase the reliability of the automaton as a whole.
The feature of this machine is to use the receiver lodgement instead of the standard trunk box. This makes it possible to more evenly distribute the arising load during shooting. Butt machine does not take the load when firing and just is the shoulder rest. Additionally serves as a key for disassembling the machine. The bottom and top cover protects the machine from getting into the dirt. The lid of the lower version is not removed, but leans back, it gives access to the trigger without disassembling the weapon. The barrel of the "Equalizer" is mounted in 2-x places - the rear end on the inner radius of the lodgment of the trunk and in the middle, in the sleeve, which is located at the base of the front sight bracket. A gas accelerator was placed in the gas pipe; it is mounted in the front area of the handle to move the machine. Fastening a bayonet is provided above the barrel, there is the prospect of mounting a grenade launcher instead.
At the moment, the grenade launcher is installed on the Picatinny rail, which is located under the barrel on a plastic forearm. Not only a grenade launcher, but also other additional equipment — a laser designator, a flashlight, range finders of various types and an additional handle — can be mounted on the bar. The handle makes holding the machine much more comfortable. Based on the design of the machine - the use of a short stroke of the barrel, mounting on the barrel of a grenade launcher of the sub-barrel type has become impossible. The rocket launcher frame is its carrier part. Therefore, a grenade launcher is limited to a grenade launcher length in centimeters 18. Loading a grenade launcher occurs with a fracture of the rear of the trunk down. By the way, such a scheme for loading a grenade allowed the use of grenades of different lengths for firing from it. A grenade launcher is locked on a simple lock, it is located in close proximity to the trigger. This arrangement makes it possible to prepare a grenade launcher for firing with one hand. USM grenade launcher samovzvodny. Clicking on the hook causes the thrust to move, which causes the cocking lever to move. The lever sets the hook to the calculated angle for cocking the spring of a combat type. At the top of the movement, the trigger comes off the lever and, under the influence of a spring, hits the cap of the grenade. The platoon lever also blocks the barrel retainer, which completely eliminates the possibility of an arbitrary opening of the barrel when firing. The sight of a portable type grenade launcher, mounted on the left of the carrier frame. The aiming bar is spring loaded and retained by the latch.
