 Small arms with uninterrupted procedure of firing (modifications), functional assemblies of small arms and method for simultaneous reduction of recoil and sound level of small arms / 2254539
Three modifications of small arms are offered. The first modification is featured by the fact that the weapon represents an attack submachine gun provided with a mechanism for a smooth strikeless release of the hammer, mechanism for a delay of the breechblock in the rear position at an empty magazine, handle-fore-grip, butt strap, the locking device is of the friction-wedge type, and the firing mechanism is of the cam double-action type with two regimes of firing with a side hammer. The second modification represents a field submachine gun provided with a mechanism for a delay of the breechblock in the rear position at an empty magazine with a breechblock stop indicator, handle-fore-grip with a retractable leg, reaction-acoustic compensator, the firing mechanism is of the striking type with two regimes of firing, it is positioned inside the breechblock and inside the return spring, and the locking device is of the friction-wedge type. According to the third modification, the small arms represent a machine gun provided with an automatic safety device actuated at a release of the fighting grip of the weapon, reaction-acoustic compensator, balancer-compensator of impact loads, mechanism for feed of cartridges from the cartridge belt to the ramming line from the bottom according to the principle of magazine systems, rod deflector of cartridge cases, mechanism for a delay of the moment of breechblock unlocking, and the trigger device of the striking type firing mechanism is made for control of the regimes of firing by the trigger. The friction-wedge locking device with the unlocking mechanism is featured by the fact that the return spring is positioned inside the breechblock and has a front stop made in the form of movable bush with side lugs passing through the slots in the breechblock wall. The cam-type double-action firing mechanism is made for accomplishment of two firing modes. The specific feature of this firing mechanism is the fact that the hammer has a spear-shaped end-piece with an annular spear-shaped shoulder, and the entire device is positioned inside the breechblock and return spring. The reaction-acoustic compensator is made with a gas dynamic or with a mechanic-dynamic control of the gas flows. In the method for simultaneous release of the weapon recoil force and decrease of the level of the acoustic component at a shot use is made of a reaction-acoustic compensator, the prebullet and pastbullet flows of powder gases are directed to the axial nozzle chambers, and then to the nozzles with a thrust vector reducing the weapon recoil force, and withdrawn to the environment through the frequency-converting gratings.

FIELD: weapons and ammunition. SUBSTANCE: self-operated gun comprises an upper part (1) and a lower part (2) of the barrel receiver. The upper part (1) the barrel receiver is fixed to the barrel (3) with under-barrel tube (4). On the front side (13) of the lower part (2) of the barrel receiver the stop (12) and the clamping screw (10) are mounted, which interacts with the upper part of the barrel receiver. The stop (12) has a cylindrical shape, it is located in the under-barrel tube (4) and is provided with a guide bevel (14), on the stop the groove (15) is also provided. EFFECT: increased reliability and accuracy of mounting the barrel receiver in the gun. 2 cl, 4 dwg
The invention relates to weapons technology, namely, self-loading rifles. Known self-loading rifle Mr-K (directory "Izhevsk mechanical plant. Baikal", 2004, p.19), containing separately made buttstock, receiver box and the base of the firing mechanism. In the butt posted by tightening screw interacting with the receiver and with the base of the firing mechanism. From rolling stock relative to the receiver protects the ledge, made in the rear part of the base of the firing mechanism, is placed in the return slot on the butt. In known self-loading rifle there is a risk of inaccurate location of the base of the trigger relative to the receiver. In addition, the high dynamic loads that occur during firing, possibly collapsing a ledge in the back of the base to the trigger and the response of the notch on the butt, what causes pitching the Foundation of the trigger relative to the receiver. All this reduces the operating characteristics of the gun. It is also known self-loading smooth-bore gun Akdal MKA 1919 ( akdal mka 1919/45-1-0-188), taken as a prototype containing the receiver box, made of two parts. To the upper part of the receiver is attached to the barrel and post the Aulnay tube. The lower part of the receiver that contains the receiver store, pistol grip, top handle and butt, made in the form of a single module. The front end face of the lower part of the receiver has a focus complex (H-shaped) configuration, interacting with mating grooves made on the upper part of the receiver. A disadvantage of the known device is that it does not prevent the possibility of pitching the lower part of the receiver relative to its upper part. The complicated form of the emphasis on the bottom and the return grooves on the upper part of the receiver complicate the process of Assembly and disassembly of weapons and reduce manufacturability. The purpose of the claimed invention is to improve the reliability and accuracy of mounting the receiver in the weapon. The problem is solved in that in a self-loading rifle, containing the upper receiver, which is attached to the barrel and underbarrel tube, the lower part of the receiver, with an emphasis on its front side, and a clamping screw mounted in the lower part of the receiver and communicating with the upper part of the receiver, according to the invention, the focus has a cylindrical shape, is placed in underbarrel tube and provided with a guiding bevel. The emphasis is made a groove. The claimed invention of lady simple and reliable design, increases the accuracy of mounting and reliably prevents rocking of the lower part of the receiver relative to its upper part, simplifies the process of Assembly and disassembly of weapons, improves manufacturability. The invention is illustrated by drawings, which depict: figure 1 - General view of the self-loading rifle section (the lower part of the receiver and the butt is made as a single part); figure 2 is a view As in figure 1; figure 3 - a view B in figure 2; 4 is a General view of the automatic guns in the cut (butt are removable). The device has an upper part 1 (figure 1) and the lower part 2 of the receiver. To the upper part 1 of the receiver is attached to the shaft 3 with a multiple-tube 4. The lower part 2 of the receiver, containing the butt 5, receiver 6 store, the handle 7 and the bracket 8, is made as a single part. In addition, the butt 5 (figure 4) may be made removable, in this case, the lower part of the receiver 2 comprises a receiver 6 (Fig 1) store, handle 7 and the bracket 8, is made as a single part. In the receiver 6 is inserted into the store 9. In the butt 5 of the lower part 2 of the receiver posted by tightening screw 10, which interacts with the rear end face 11 of the upper part 1 of the receiver. A cylindrical stop 12 is the front end face 13 (2) of the lower part 2 of the receiver, placed in underbarrel tube 4 and has sent the second bevel 14 (the direction of the cartridges into the cartridge chamber of the barrel). In addition, in the upper part of the cylindrical lock 12 is a groove 15 at the crest of a shutter (not shown). When assembling the weapons you want to insert a cylindrical focus 12 (1) of the lower part 2 of the receiver in underbarrel tube 4, is attached to the upper part 1 of the receiver: to combine the upper 1 and lower part 2 of the receiver and fasten the two parts of the receiver coupling screw 10. 1. Self-loading rifle, containing the upper receiver, which is attached to the barrel and underbarrel tube, the lower part of the receiver, with an emphasis on its front side, and a clamping screw mounted in the lower part of the receiver and communicating with the upper part of the receiver, wherein the stop has a cylindrical shape, is placed in underbarrel tube and provided with a guiding bevel. 2. A semi-automatic rifle according to claim 1, characterized in that the emphasis is made groove.
