The invention relates to small arms and can be used in military equipment.

Known automatic rifle, made by the "classical" scheme with a constant or a folding butt stock and pistol grip fire control, located between the butt and the store (http://world.guns.ru/assault/rus/ak-74-r.html).

The lack of "classic" scheme is the large length of the weapon and reduced accuracy in the automatic fire (for weapons, where the axle shaft is located above the axis of the butt).

Known machines, made by the bullpup configuration, in which the control handle fire with a trigger located on the forearm (http://world.guns.ru/assault/rus/ots-14-groza-r.html; http://world.guns.ru/assault/isr/tavor-tar-21-r.html; http://world.guns.ru/assault/ua/verp-r.html; http://world.guns.ru/assault/ch/type-95--qbs-95-r.html).

The disadvantages of this scheme is the center of gravity of the weapon in the back, the inconvenience of loading and use of the fuse, no butt, necessary when firing lying down and in hand-to-hand combat.

The closest analogue to the claimed is "Automatic weapons "Kalashnikov" (Eurasian patent # 000020; AK-74M)containing the receiver box, the trigger mechanism (USM), locking mechanism, vent mechanism, folding buttstock with stoppers fighting and marching provisions trunk with block scope, sighting Blanco and stable flies; store, the magazine release, grip firing.

AK-74M has a folding plastic hollow butt, rollaway left side and a locking latch.

Disadvantages AK-74M are: large length when laid out in a fighting position the butt, causing rapid ustawianie arrow when target shooting standing; reduced maneuverability in cramped conditions; the difficulty of fire in the transport position with the butt folded; reduced accuracy due to the mismatch of the axis of the barrel and points of emphasis in the shoulder butt; a significant increase in the load on the arrow with the use of additional devices, silencers, tactical flashlights, scopes, etc.

To eliminate these disadvantages it is proposed to combine the classical scheme with a bullpup configuration, with the possibility of using one weapon of both schemes that will allow the transport position to produce a targeted shooting, will increase the accuracy, reduce the workload on hand arrow will reduce the size of the weapon when it is used in cramped conditions, will facilitate aiming at the use of body armor and helmets with face shield and bulky winter clothing and at the same time will preserve the possibility of using a rifle butt.

This weapon is equipped with an additional trigger and aimed to fit what TableName, allowing aimed shooting, as with butt, spread in a combat situation, and with the butt folded in the transport position, and activating (translation additional devices from the transport in the military for shooting from bullpup") does not exceed 6-10 seconds.

So, for option 1, the inside of the butt is craving, pivotally connected with a turning fork and additional trigger, located on the left side of the stock near the butt-plate in the Y-shaped groove and slide out of the groove perpendicularly above the side surface of the butt of 1.5-2.5 cm when turning the plug under the action of the spring 90^abouton the left side of the butt, the forked end of which, when closing the butt on the latch captures the main trigger of the machine. Additional trigger, when it is moved into position in front of the store under the end of the receiver at a distance of about 2 cm

The standard iron sights of the AK-74M installed rack, made in the form of rotary parts, a locking spring. On the rear sight rear sight on the two axes is set folding peep sight, and modified polozok main fly - swivel stand for more flies. On the magazine release button is mounted a spring-loaded on orotina space. On the butt and the butt latch installed additional sling attachment that secures the rubber damper. On the receiver cover attached elastic strap to stop her cheeks from the porous material and the gas shield made of a springy heat-resistant film, fixed on the side surface of the spring cover plate with lock for T-shaped rivets.

So, for option 2, in the lower front part of the receiver, in front of the shop in the pie hole on the axis of the latch butt has a swing arm with a rack on which the hinge is an additional trigger with lock horizontal and vertical positions, and a lever connected with the main trigger pull missing on the left side inside the receiver, with additional trigger secure additional removable trigger guard, consisting of two pivotally United, apart, spring parts, and additional sights, magazine release button, rubber damper, plate cover of the receiver, a gas screen, repeat option 1.

Accessories do not affect the basic functioning mechanisms of the weapon.

Accessories include: additional trigger (13)located in the butt (9), swivel pad latches store (14), peep sight (15), rotary rack additional flies (16).

Additional trigger (13) is located inside the hollow butt (9) (1, 2, 3, 4, 5, 8, 9,10,11) and consists of a rotary plug (17) (Fig), thrust (18) (Fig), the trigger (19) (Fig) and retainer (20) (Fig) swivel bracket. In the lower side of the butt (9) has a shaped opening (21) for output on the left-side surface of the additional sposobov the hook (19), having a curved bottom portion (22), repeating geometry of the trigger, and parallel to the lower part of the receiver part, made in the form of a groove (23), the size corresponding to the diameter of the cylindrical part (24) of the trigger. At the bottom of the butt has a window (25), through which out dated rod (18). Axis (26) of the rotary plug (17) in the holes (27) (28) and fixed lock washer (29). On the axis (26) has a slot (30)in which there is an end (31) of the spring (32), working on twisting. The second end (33) of the spring (32) rests on the inner surface of the butt (9). Between a plug (17) and the rod (18) pivotally connected by a shaft (34) with the possibility of rotation.

The trigger (19) is connected with a pull (18) axis (35). The end of the tie rod (18) has a stop (36), which limits the possibility of rotation on the axis (35) of the trigger.

The latch (20) of the plug (17) (Fig) made in the form of a cylindrical rod of variable diameter, at the lower end of which has a cap (37), the diameter of which is slightly larger than the inner size of the groove (38) of the plug (17), and on the upper end of the groove for the locking washer (39). The latch has a spring (40), rests on the upper inner surface of the butt and push the cap (37) from the hole (41).

To provide the necessary elevation of the trigger (19) on the side surface of the butt () in its lower part inserted emphasis (42) additional trigger made in the form of a wedge (Fig).

Rotary Playground (14) (Fig) latch hinged to store the modified magazine release button that is different from the standard (pigv), the presence of protrusions (43) with a hole (44) for the axis (45) of the rotary platform, which is also the spring (46)which presses the rotary platform (14) to the surface of the latch (5)directed to the store. Spring (46) is not very hard and makes it easy to rotate the platform (14) on an axis (45). Playground (14) serves to support the upper surface of the right-hand arrow (between thumb and index finger) while holding the weapon by the magazine, when shooting with the additional trigger (19). When pressing on the lower end of the ground (14) below, it is deflected at the angle at which its lower surface is set parallel to the surface of a support (hands). When removing hands from the store, spring (46) returns a space (14) in a vertical position. In this position, the protruding edge (47, 47') allow exemption store by clicking on them forefinger or middle finger of the hand holding the handle of the fire control (2). Also Playground (14) allows you to change the store as usual, by pressing on the lower part of the thumb that is holding the store.

Peep sight (15) (Fig a,b,C,d,e,e,W) consists of sighting the Lanka (6), in the lower part of the pillar which, across, located axis (48,48')made integral with a whole; bracket (49) with diopter (50), the locking washers (51, 51') and lock washers (52, 52').

Axis (48, 48') are adjacent to the rear cylindrical sections (53, 53'), the ends of which pass into hexagons (54, 54')having grooves (55, 55') under lock washers (52, 52').

Bracket (49), made of spring steel, in the middle part has a deck with diopter (50), and at the ends of the openings (56, 56'), corresponding to the diameter of cylindrical sections (53, 53') axes (48, 48'). Perpendicular to the axis of the holes (56) on the outer sides of the bracket (49) have grooves (57, 57'), performed to a depth of half the thickness of the bracket (49) in the form of a cross, or another shape having a rotary symmetry 90^about.

The locking washer (51, 51') have hexagonal openings (58, 58'), corresponding to hexagons (54, 54') axes (48, 48'). One side of the washer has projections (59)located in the form of a cross and protruding above the surface of the washer on the value of grooves (57, 57') of the bracket (49). The dimensions of the projections (59) match the dimensions of the grooves (57, 57') of the bracket (49), and when the imposition of tightly into each other, forming a claw clutch.

Cylindrical sections (53, 53') have a length equal to the thickness of the bracket (49) and projections (59) washers, and Allen (54, 54') have dimensions corresponding to the thickness of the locking washers (51, 51') (without the Uch is one of the protrusions (59)). The size of the working length of the hexagons (54, 54') limit grooves (55, 55'), lock washers (52, 52').

The ends of the bracket (49) in the free state are not parallel to each other and some from the sides, under the action of the elasticity of its material. When mounted on shafts (48, 48') of the ends of the bracket (49) divorced in hand and put on the ends of the axle shafts (48, 48'). Next, the ends of the bracket (49) is compressed. On the hexagons (54, 54') put the locking washer (51, 51'), tabs (59) in the direction of the grooves (57, 57'), mirror-symmetrically to each other, and are fixed in the grooves (55, 55') locking washers (52, 52').

Clenching the ends of the bracket and rotate it 90^aboutrelative to the plane of rear sight (6), bracket (49) into the position in which the grooves (57, 57') coincides with the position of the tabs (59) locking washers (51, 51') and under the action of elasticity of the material of the bracket grooves (57, 57') its ends are engaged with the protrusions (59), washers (51, 51'). This selects all the backlash and bracket (49) is fixed on the axle shafts(48, 48') without a possibility of rotation. While the dioptre (50) is installed vertically in a fixed position above the aiming bar, allowing you to aim through it when transferring weapons to "bullpup or through the rear sight rear sight (6), with the classical scheme of the use of weapons, not interfering with each other. For translation peep sight (15) in NEA is tipirovanie position the ends of the bracket (49) to compress the output from engagement in the grooves (57, 57') of the projections (59), washers (51, 51') (Fig g, pressing the ends of the bracket (49) on the arrows)and turn handle (49) down into the side of the receiver of the weapon until you hear a click - in a position in which the engagement grooves (57, 57') with protrusions (59) washers when turning on the 90^about. For translation in the activated position all repeat in reverse order.

Swivel hour additional flies (16) (Fig a, b; 20, 21, 22, 23) has an axle (60) (modified polozok main fly with a threaded hole (61) for fastening the main fly (62) weapons), the ends of which are similar to the design of the peep sight (15), there are hexagons (63, 63'), grooves (64, 64') and lock washers (65, 65'). On the hexagons (63, 63') put the locking washer (66, 66')with hexagonal holes (67) and cross tabs (68), protruding above the surface of the washers (66, 66') at half the thickness of the bracket (69) swivel stand (16).

Bracket (69) is made of spring steel and in a free state, its ends are not parallel, and separated by some angle (Fig b).

On the side of the bracket (69) additional fixed front sight (70) on the bracket (71).

At the ends of the bracket (69) has holes (72), corresponding to the diameter of the axis (60). On the outer surface of the ends of the bracket (69) around the holes (72) has a cruciform grooves (73, 73'), whose dimensions match the dimensions of the invoice the surface (68) locking washers (66, 66'), forming a claw clutch.

Assembly and turns in swivel extra flies (16) is similar to the Assembly and turns in the desired position design peep sight (15).

Bracket additional front sights (71) (Fig) made of soft steel, capable of plastic deformation. It is made in the form of a single part having a pad (74) for mounting on the side wall of the bracket (69) rivets (75) and bending (76), which is an additional fly (70) and corrector (77) the provisions of the flies, in which there is a hole (78), the size matches the diameter of standard punch (79) weapons. For position correction flies (70) the end of the punch is introduced into the hole (78) and, deforming the curve (76), set the aperture to the correct position when the zeroing.

To improve comfort of use of weapons on the bullpup configuration, also on the weapon mounted rubber damper (80) (1, 2, 3, 4, 5, 24 a, b) receiver back plate, the cover plate (81) on the receiver cover and the gas screen (82).

Shock (80) (2; 3; 4; 5; 24 a, b) is made in the form of a flat elastic plate (83) with lugs (84, 84') at the ends. In eyelets inserted sling attachment (85, 86), one of which (85) is fixed in the axis of the latch butt, and the second at the end of the butt, next to the hinge. The middle part of the plate (83) wider than its ends and, when closing the reclad, it completely covers the back plate of the receiver and hangs a little over the top arm (2). While the sharp corners of the back plate are smoothed out, and his emphasis on the shoulder becomes comfortable. With the opening of the butt, the shock absorber is formed in a ring on the right side of the weapon, without interfering with the shooting in the "classic" version (figure 4).

Plate (81) (1, 2, 3, 6, 7, 24 a, b) on the receiver cover (12) made of polyethylene or other similar material in the form of a half pipe and is attached to the lid using double-sided tape (87), pasted on the cover. When applying cheek to the plate (81), when aiming, the dioptre (50) and additional fly (70) are mounted on the same axis with the eye arrow ensuring accurate shooting. The strap also eliminates the discomfort associated with temperature effects and impact loads when fired.

Gas screen (82) (figure 1, 2, 3, 6, 7, 24 and, 6, 25) is formed in the shape of half pipe film of polyimide or other material having similar mechanical properties, one end of which is fixed on the top left of the cover (12)from the side of the barrel, pressure plate (88)fixed on the T-shaped rivets (89), pear-shaped holes (90), through hole (91), and the second dangle from the right side of the cover, partially overlapping window is La ejected, without interfering, however, the cocking handle bolt carrier Assembly. Pressure plate (88), made of spring steel, on the right end has a stop (92) and a hook (93), which pressure plate is fixed in the groove (94) cap (12).
