The invention relates to weapons technology, systems of automatic firearms and can be used in smoothbore guns and rifled the machine-guns. Famous submachine gun PPSH-41, in which the locking shaft is provided with one spring-loaded inertial shutter [A.B. Zhuk Small arms. Revolvers, pistols, rifles, submachine guns, machine guns. - M.: Voenizdat, 1992. - 735 S.: ill. s]. The disadvantage of such a system lock prevents the use of large ammunition capacity. A well-known gun "Parabellum" with locking barrel system of levers with the copier located above the handle [A.B. Zhuk Small arms. Revolvers, pistols, rifles, submachine guns, machine guns. - M.: Voenizdat, 1992. - 735 S.: ill. s]. The locking shaft is provided by a system of levers the dead point position. During the shot when you step backwards moving parts, levers come up against the fence, climb up and the bolt is unlocked. The disadvantage is that the levers are located on the movable frame, not closed and the probability of clogging and failure of the weapon. Famous machine gun MG-42 [Babak F.K. Guns / F.K. Babak. - M.: ACT; SPb.: Polygon, 2006. - 335 S., s]. Automatics are operated by the recoil of the barrel during its short course. The breech is two fights the mi rollers, which are curved grooves boxes. The disadvantages of this gun are: significant weight, complexity of the device separate nodes (the locking mechanism, shutter mechanism, the shutter) and the whole gun in General, large volume production of almost all items, the sensitivity of the gun to pollution and big recoil when fired. Closest to the proposed invention (prototype) is a submachine gun MP-5, developed by the German company Heckler and Koch" [V. Grytsenko, Fedoseev S.L. Weapons infantry.- M: Arsenal Press, 1997. - 400 S.: ill. s], [Shunkov, NR. Encyclopedia latest small arms / V.N. Shunkov. Under the General editorship AU Taras. - M.: ACT, Mn.: Harvest, 2006. - 560 S.; Il., s]. The locking system of the machine gun MP-5 is similar to the MG-42. The bolt submachine gun MP-5 consists of two main parts and has rollers protruding from the side faces of the lower part (larvae) of the shutter. The more massive the upper part presses the larva in its extreme rear position. When the shot rollers disposed in side, in the slots of the receiver, thereby locking the shutter. The disadvantage of this system of locking is to return the shot, because the accelerating movement of the parts of the shutter are directed in the direction of impact. The technical result of using the present invention, t is aetsa reduce the recoil, which is achieved due to: - use two paddles (upper and lower inertia) with their return springs that provides energy absorption impact; - inverter connecting the two gates with different arm lengths, which ensures rapid roll forward of the lower inertia of the shutter, which reported significant kinetic energy directed in the direction opposite to the recoil that provides the energy absorption of the recoil. The speed of movement of the lower shutter several times greater than the speed of movement of the upper shutter; - inside the upper shutter is fighting the emphasis in the form of a lever on an axis of rotation which receives the pressure of the powder gases from the top of the shutter and transmits this pressure to the inverter, and after disconnection of the combat focus with inverter upper shutter due to the residual pressure of the powder gases rolled back to the end position. Other advantages of the present invention: - easy replacement of the barrel in case of overheating, as the trunk except flies and handles there are no additional mechanisms and units; - placing mechanisms of energy absorption impact inside the butt, does not increase the length of the weapon. The technical result is achieved by automatic small arms has two shutter is their return springs, connected the inverter to the axis of rotation, mounted at the rear of the butt and having a different length levers about the axis of rotation, with the upper gate, inside of which is placed a combat emphasis on the axis of rotation, slides over the top rails of the receiver, and the lower inertia of the shutter on the end has a D-shaped glides on the bottom rails of the receiver and near the trigger on the receiver are equipped with shock absorbers brake. The absorber braking can be pneumatic, hydraulic or made in the form of buffer springs. When using powerful ammunition you can apply multiple braking devices. 1 shows a General view of the automatic fire weapons, MAGE-2, which shows the barrel 1, stock 2, a handle for holding 3, the sighting device 4, shop 5, the receiver box 6. Figure 2 shows the barrel 1 and the receiver box 6 with the upper and lower guides. Figure 3 shows the weapons in the context of: the barrel 1, the receiver box 6, the upper stopper 7 with the return spring 8, the knob for distortion 9 with its axis of rotation 10, the lower shutter 11 with the return spring 12 and the absorber 13. Shows the inverter 14 with the axis 15, consisting of an upper and short lower long arms. There is a battle stop 16 with the spring 17 and the axis of rotation of bewag the stop 18. Figure 3 also shows the trigger mechanism 19, which has the trigger 20 and the trigger 21. The receiver is installed, the copier 22. For the shot you want to take the weapon in the hand by the handles for holding 3 (1), insert the store with 5 cartridges and pen for distortion 9 (3) pull the upper shutter 7 back to the rearmost position. When the trigger 20 in the firing mechanism 19 is fighting trim. (Figure 3). Next, the compressed return spring 8, the upper shutter 7, the handle 9 is turned on its axis 10, the effect on the morale of the stop 16, which rotates on its axis 18 and compresses the spring 17 the fighting stops. When the fighting stops 16 rotates, end rises and disengages from the inverter 14 and the unlocking of the upper shutter 7. When releasing the handle 9 on the bolt 7, under the influence of the return spring 8, the movement of the shutter 7 and the upper rail of the receiver in the extreme forward position, this retrieves the cartridge from the magazine and shall be expedited a round in the chamber, and the lower inertia of the shutter 11 remains stationary. When pressing the trigger 21 of the trigger 20 strikes the striker, destroys capsule and is shot. The pressure of the powder gases affects the upper stopper 7 and through the fighting stops 16 presses on the top of the short arm of the inverter 14 and the inverter 14 beg the onset rotated on the axis 15, and lower long end of the lever imparts acceleration of the lower inertia of the shutter 11 and it compresses the return spring 12. As turning of the inverter 14, the upper stopper 7 with a force stop 16 will go back up until the copier 22 has no effect on the fighting stops 16, will cause it to rotate on its axis 18, to compress the spring 17 and outputs it from engagement with the inverter 14. Without encountering obstacles in its path, the upper stopper 7 on the upper track due to the residual pressure of the powder gases in the barrel will move to its rearmost position, together with the fighting stops 16 and compress its return spring 8. When movement occurs the extraction and ejection of the empty case from the chamber and the trigger Assembly 20 in the firing mechanism 19. When the motion of the upper shutter 7 forward combat focus 16 does not prevent its forward movement, is another removing the cartridge from the magazine and ramming it into the chamber. The upper locking bolt 7 is possible if the following two conditions: when the forward movement of the upper stopper 7 from the influence of its return spring 8 has an extreme forward position, the spring 17 acts to combat the stop 16, which rotates on the axis of rotation 18, combat focus comes into contact with the short arm of the inverter 14 and the locking of the barrel 1 top ZAT is a PR 7; - lower the shutter 11 in the rotation of the inverter 14 on the axis 15 receives the shot significant acceleration and moves forward on the bottom rail of the receiver in the direction of the bullet, when it absorbs the recoil energy becomes significant kinetic energy. When the forward movement of the lower inertia of the shutter 11 compresses its return spring 12, gives the kinetic energy of the braking device 13 mounted on the receiver and returns to its rearmost position, cranks the inverter 14, acting on its long arm, the inverter turns on the axis 15 and the upper short end comes in contact with the fighting stops 16 and locks the upper stopper 7. Automatic small arms, including the barrel, receiver box, shutter return spring, the trigger, the sights, the release mechanism and the ejection cartridge, store, handle bag, characterized in that the automatic small arms has two gates with their return springs connected inverter on the axis of rotation, mounted at the rear of the butt and having a different length levers about the axis of rotation, with the upper gate, inside of which is placed a combat emphasis on the axis of rotation, slides over the top rails of the receiver, the lower the inertial breech end has an l-shaped form glides on the bottom rails of the receiver, and near the trigger on the receiver are equipped with shock absorbers brake - pneumatic or made in the form of buffer springs.
