(RF patent No. 55116 MKI: F 41 C 23/04 date of publication. 07.27.2006)

This model is chosen as a prototype.

This butt, pivotally mounted on the fork of the back of the receiver (hereinafter referred to as the base of the receiver), is folded onto the side of the weapon and fixed in the combat or traveling position using a spring-loaded rotary latch with a fixing tooth, and the tooth interacts with an emphasis on the butt with the possibility of holding it in the stowed position and is in contact with another focus in the combat position, the butt eye is spring-loaded relative to the lower part of the fork of the base of the receiver, fixed iruyuschy tooth has a conical shape and extends from the inner surface of the upper part of the fork, and the response provided on the upper surface of the butt with lugs diametrically opposite sides, forming a spring-loaded latch combat and stowed positions. The disadvantages of the prototype model are the lack of a pistol grip for aiming and fire control, as well as the butt is inconvenient due to the inability to adjust its length for the anthropometric data of the shooter, which significantly reduces firing efficiency and ease of use of weapons.

The technical task of the proposed utility model is to eliminate these drawbacks, namely, to increase the reliability, convenience and efficiency of using the MP-153 hunting rifle using a folding stock.

The technical result of solving this problem is achieved by the fact that the folding butt for MP-153 contains the base of the receiver, made at the same time with a plastic pistol grip, connected to the gun by means of a screw screwed into the standard screw hole of the gun part of the receiver, the butt frame and, between the base and a frame, a swivel hinged folding butt with a locking latch of the combat and marching positions of the butt. The butt frame is made of steel tubes with an end plate covered with a layer of plastic. The triangular shape of the butt frame provides it with mechanical strength. In the back of the butt is attached a shoulder rest in the form of an elastic shock-absorbing butt pad, softening the blow during recoil and increasing the usability of the weapon. Between the butt plate and the butt can be installed spacers, changing the number of which you can adjust the length of the butt, adapting it to the anthropometric characteristics of the shooter.

The essence of the utility model is illustrated by drawings:

figure 1 is a General view of the stock in combat position;

figure 2 - General view of the butt in the stowed position;

figure 3 - attachment butt to the base of the receiver (combat position).

The folding butt MP-153 (Figs. 1, 2, 3) contains the base of the receiver 1, made integral with the pistol grip 2, the frame 3 with a spring-loaded elastic element 4, an eye 5, pivotally mounted on a fork 6 of the back of the base of the receiver, a latch marching and fighting positions, which is

fixing tooth 7 on the inner surface of the fork. Tooth 7 (figure 2) interacts with an emphasis made in the form of a groove 8 on the eye,

fixing the butt in the stowed position. When translating the stock in the combat position, the tooth 7 interacts with another focus - the groove 9 (Fig.1, 3). The grooves 8 and 9 are made on the upper surface of the eye of the frame 5 from diametrically opposite sides and, when in contact with the fixing tooth 7 of the fork, are spring-loaded latches of the combat and traveling positions of the butt.

The frame 3 with the eyelet 5 fixed on it is pivotally mounted on the fork 6 of the rear of the base of the receiver using the vertical axis 10. In the rear of the frame to absorb shock impact, an elastic butt plate 11 is mounted on the screws with the possibility of installing spacers 12 between it and the frame, changing the number of which you can adjust the length of the butt. On the side of the butt frame there is a swivel 13 for attaching a belt for carrying weapons. The butt is attached to the gun by means of a screw 14 (Fig. 1) on the base of the receiver 1 to the standard threaded hole on the rifle of the receiver.

Pistol grip 2 is used for aiming and fire control, increases firing efficiency. The handle has an ergonomic section, a notch is made on its lateral surfaces, which reduces the sliding of the handle in the hand of the shooter. In the internal cavity of the pistol grip there is a housing and a box-cover 15, equipped with a cavity for storing batteries for a tactical flashlight.

The principle of operation of the folding butt.

In the combat position (Figs. 1, 3), the buttstock frame 3 is held on the base 1 by an axis 10 passing through the hinge fork with a fixing tooth 7 included in the response stop - groove 9 of the eye 5, pressed by a coil spring 4. The conical shape of the tooth 7 and groove 9 and ensuring their adhesion by the spring 4 allow you to choose available in

swivel clearance, providing structural rigidity, which improves the quality of shooting.

- To transfer the stock from the combat position to the stowed position, it is necessary to press the frame 3 vertically downwards, compressing the spring 4, disengaging the tooth 7 and the conical groove 9 (Fig. 3), and turn the frame 3 on the axis 10 to the left in the direction of the muzzle. At the same time, the frame rotated through 180 ° brings its second groove 8 (Fig. 2) of the eyelet 5 to the fixing tooth 7 of the fork, which are engaged and, under the influence of the spring 6, are held in the stowed position.

To translate the butt from the stowed position to the combat position, it is necessary to press the frame 3 vertically downwards, compressing the spring 4, disengaging tooth 7 and the conical groove 8 (Fig. 2), and rotate the frame 3 on the axis 10 backwards from the muzzle by 180 °. In this case, the tooth 7 of the plug 6 enters the first groove 9, the spring-loaded eye of the frame eye 5, and the butt is fixed in the fighting position (Fig. 1).

The vertical location of the axis of rotation 10 allows you to fold and put into combat position weapons with the store, which is an important factor for reducing production time with a sudden need for firing.

The use of the folding MP-153 proposed as a useful model of the butt provides rigidity, improves reliability, performance and versatility of weapons.
