TECHNICAL FIELD
The invention relates to the field of guns technology and can be used in firearms with magazine feeding.
BACKGROUND OF THE INVENTION
The known firearm U.S. Pat. No. 2,213,28, where the magazine is located in a longitudinal vertical plane passing through the longitudinal axis of the barrel. This design does not allow to bring the breech closer to the trigger, as a result of which there is no way to shorten the length of the firearm.
Firearms systems with a lateral magazine location U.S. Pat. No. 1,450,834A, DE4317310 (A1), in which the magazine is inserted from the side into the protruding part of the receiver, which leads to a significant increase in the transverse dimensions of the firearm.
Also known firearm U.S. Pat. No. 1,376,694A has a magazine located in the inner cavity of the receiver eccentrically relative to the vertical plane, which increases the transverse dimensions of the receiver, and the magazine itself is inserted from below, which complicates the operation of the firearm.
In addition, the receiver and the stock have a configuration that does not allow to bring the breech end to be closer than the length of the cartridge used in this firearm, the length of which in some cases exceeds 140 mm.
DISCLOSURE OF THE INVENTION
The proposed invention solves the problem of reducing the length of the firearm by approaching the breech end of the barrel to the trigger at a distance less than the length of the cartridge.
For this, the magazine is located outside the longitudinal vertical plane passing through the longitudinal axis of the barrel and is displaced in the direction of the stock, which also allows the breech end to be displaced to the trigger by a length of 70 mm or less.
At the same time, to ensure the convenience of attaching the magazine and reducing the transverse dimensions of the firearm, the magazine is placed in a cutout made on the lateral surface of the receiver.

THE BEST EMBODIMENT OF THE INVENTION
Firearm (FIG. 1, FIG. 5, FIG. 6, FIG. 7) contains a barrel 1, a bolt 2, a receiver 3, a firing mechanism 4, a magazine 5 for cartridges 5.1 (FIG. 3), a stock 6.
Receiver 3 (FIG. 2) contains a channel 3.1 for placing the barrel 1, a channel 3.2 for placing a bolt 2, a cutout 3.5 for placing a magazine 5 (FIG. 4), a lateral surface 3.10.
Magazine 5 (FIG. 3) is designed to accommodate cartridges 5.1.
The magazine 5 is installed in the cutout 3.5 of the receiver 3 according to the diagram on FIG. 4.
The magazine 5 installed in the firearm (FIG. 5) is located eccentrically relative to the vertical plane Y passing through the longitudinal axis of the barrel 1.
The magazine 5 installed in the firearm (FIG. 6) is located in such a way that its elements do not protrude beyond the lateral surface 3.10 of the receiver 3.
The breech end 1.2 of the barrel 1 (FIG. 7) is located relative to the trigger 4.1 of the firing mechanism 4 at a distance of T, which is not more than 70 mm.
Variant (FIG. 8) of the firearm, when the firing mechanism 4 is attached using parts 32 directly to the breech 1.1 of the barrel 1.
A variant (FIG. 9, FIG. 10) of the firearm, when the base of the sighting devices 10 is installed directly on to the barrel 1. The scheme of the installation (FIG. 10) of the sighting devices 10 directly on the barrel 1.
The magazine 5 (FIG. 11) of the firearm contains a cutout 5.2, so that the magazine 5 does not overlap (FIG. 12) the cutout 6.1 in the stock 6.
A variant (FIG. 14, FIG. 15) of a firearm, when the barrel 1 is installed in the receiver 3 and is fixed with parts 30 and 31.
For this, the receiver 3 (FIG. 13) has a channel 3.1, into which the barrel 1 is placed, a slot 3.4.
In this case, the channel 3.1 and the slot 3.4 form a clamp connection, which is clamped by the parts 30 and 31 (FIG. 15, FIG. 14) passing through the holes 3.3 (FIG. 13). Installation diagram (FIG. 15) of the barrel 1 in to a firearm.
