1 . Automatic weapons, arranged according to the bullup scheme, contain a barrel, a barrel box in the form of a cylinder passing into a rectangular box, a mechanism for moving a cartridge from the magazine into a chamber, which is a part of a chamber, in the form of a drum, which features open chambers, where the cartridges come from the store vertically, the trigger mechanism including the piston rod of the gas tube, which is the drummer and the shaft of the drum, the bolt, the shock spring, the spring of shock, the stem hooking frame behind the release mechanism, rocking mounted on the axis of the frame, moving along the grooves of the cylindrical receiver horizontally and connected by a plug to the drum, a gas outlet mechanism with a gas tube and a piston in which gases are directed towards the muzzle, a return mechanism, a multipurpose store of increased capacity that supplies bullets to the machine vertically, and which has functions of a butt and armored plates when carrying spare shops on the body of the fighter. 
     
     
         2 . The automatic weapon of  claim 1  is characterized by the moving mechanism of the cartridge from the magazine to the chamber, which is done in the form of a drum with open chambers, and is located in a cylindrical receiver, which is part of the chamber and is intended for receiving a cartridge coming from the magazine into the mechanism vertically, and also feeding the bullet, which is a part of the sleeve into the chamber of the barrel by rotating the drum around its own axis and traversing it along this axis. 
     
     
         3 . The automatic weapon of  claim 1  is characterized by the barrel which is in the form of a cylinder that is a casing for the drum, has a thickening in the upper part to perform the function of the chamber, which prevents the cartridge from falling out of the open chambers and has two rectangular windows for receiving the cartridge and ejecting the cartridge cases. 
     
     
         4 . The automatic weapon of  claim 1  is characterized by the main part of the trigger mechanism that is in the front part of the submachine gun in the rectangular receiver, where the piston rod is the impactor and simultaneously is the piston axis of the gas tube, the shock spring, the trigger mechanism, the spring, the bolt and the drum. 
     
     
         5 . The automatic weapon according to  claim 1 , characterized by the rod which is rigidly connected to a frame that moves horizontally through the grooves of the rectangular receiver and, when the piston rod moves under the action of the powder gases to the muzzle, the impact spring is compressed and held in a compressed state as a result of the fact that the frame of the rod is engaged with the trigger. 
     
     
         6 . Automatic weapon of  claim 1  is characterized by the gas tube that is attached downwardly to the barrel, wherein the powder gases from the barrel enter the tube through its rear part and the front part is directed towards the muzzle so that the piston with the rod under the action of the propellant gases moves in the direction of the muzzle, significantly compensating the return of the shot. 
     
     
         7 . The automatic weapon of  claim 1  is characterized by the trigger which is in the form of the letter “T” and is hingedly attached to the frame moving horizontally along the grooves of the cylindrical receiver through the axis passing through the center of the perpendicular and the rear plug together with the drum due to the connection with the left cylinder of the drum with a fork placed between the two washers of this cylinder so that it does not rotate when the drum rotates, wherein the lower part of the trigger enters the slot tube of the rear plug and is supported to the slot of the left cylinder of the drum by a return spring. 
     
     
         8 . The automatic weapon of  claim 1  is characterized by the right upper end of the trigger which is a striker and the left one, when the striker strikes the capsule, the locking mechanism of the drum actuates and the drum is unlocked when the trigger is retracted to the vertical position and the locking mechanism returns to the initial state. 
     
     
         9 . The automatic weapon of  claim 1  is characterized by the return spring which sets the trigger to a vertical position, pressing it against the rear surface of the left cylinder of the drum and, influencing the trigger, pushes the drum forward to the barrel. 
     
     
         10 . The automatic weapon of  claim 1  is characterized by the rear plug of the cylindrical portion of the receiver which is inserted inside this box, has longitudinal grooves aligned with the slots of the receiver in which the hammer frame moves, wherein a tube is attached to the center of the plug with a transversal vertical cut, which is the axis of the drum and the guide of the return spring, and the lower part of the trigger is inserted into the cut. 
     
     
         11 . The automatic weapon of  claim 1  is characterized by the hollow rod which is in the form of a tube, which is the storage location of the ramrod, which serves to cool the piston rod and piston. 
     
     
         12 . The automatic weapon of  claim 1  is characterized by the multifunctional high-capacity magazine which has several clips inside the box body and feeds the cartridges vertically to the drum due to the lack of holding bows in the clips, fixing the clip spring in the lower position by inserting the feeder rolls into the horizontal grooves, as well as holding the cartridge in the cage by locating the clips in the store box and the shop window lid. 
     
     
         13 . The automatic weapon of  claim 1  is characterized by the multifunctional magazine of increased capacity for fastening to the machine has horizontal grooves and a vertical grip in the front part from the transverse rolling. 
     
     
         14 . The automatic weapon of  claim 1  is characterized by the multipurpose store of increased capacity, wherein the ejection capsule of the empty clips is attached to the wall of the magazine at such an angle that the cartridge is ejected forward and upward so that the capsule does not rest against the hand of the shooter. 
     
     
         15 . The automatic weapon of  claim 1  is characterized by the multifunctional store of increased capacity which serves as a buttstock, and the function of armored plates on the bulletproof vest when carrying the arrow of spare shops on the body.
