Description

The invention relates to weapons technology, in particular to Kalashnikov assault rifles and their civilian counterparts, such as Saiga and Vepr carbines, and can be used to modernize them by installing optical sights.

A device for mounting a sight on a Kalashnikov assault rifle is made in the form of a side bar for mounting night sights (1), rigidly fixed to the left side of the receiver using three rivets. The disadvantage of this device is that its use on Kalashnikov assault rifles with a folding butt requires removing the mounted sight every time when folding the butt. In addition, the use of this device requires the use of sights of a special design having a side bar made as a unit with the body of the sight, which does not allow installing such sights on other types of weapons, for example, the M16 rifle (USA), the ΙΝ8Α8 rifle (India) with the top the bar. The installation of universal sights on a Kalashnikov assault rifle equipped with a side rail requires the use of an additional side bracket, which impairs the weight and size parameters of the weapon and reduces the mechanical stability of the optical sights due to the presence of additional mechanical connections.

A device is known for mounting a sight on a Kalashnikov assault rifle (2), made in the form of a bar mounted with clamps and four screws on the barrel of a weapon between the base of the front sight and the gas chamber. The disadvantage of this device is the large removal of the bar forward, which requires the use of special optical sights, which have limited optical characteristics (field of view, magnification, etc.). In addition, this installation is not recommended by the developers of weapons due to large vibrations and significant overheating of the bar and scope, which sharply reduces the accuracy of shooting.

It is also known a device for mounting a sight on a Kalashnikov assault rifle (3), made in the form of a bar mounted with a pair of clamps and four screws on the gas outlet of the assault rifle. The disadvantage of this device is the possibility of overheating during firing (up to 300 ° C) due to close contact with the gas pipe of the specified bar and sight, which affects both the accuracy of the shooting and its service life. In addition, since the bar and the sight mounted on it are removed from the shooter's eye, this sharply narrows the class of sights that can be used for installation on this device.

The closest in technical essence is a device for mounting optical sights on a Kalashnikov assault rifle (4), containing a Ruayiiu-type strap mounted with rivets on the receiver cover, and a stabilization unit made in the form of two bushings rigidly mounted on the front of the receiver, which are connected to a sleeve located on the machine body in front of a mechanical sight, forming a swivel. The specified device provides a rigid fixation of the sight on the body of the machine and stable accurate shooting. A disadvantage of the known device is the need for its manufacture and installation in an arms factory, i.e. actually requires a change in the design of the machine, which does not allow it to be used to modernize more than 60 million previously issued Kalashnikov assault rifles.

The objective of the invention is to provide a device for mounting a sight on a Kalashnikov assault rifle, which provided rigid fixation of the bar on the receiver cover and guaranteed the stability of the sight relative to the barrel of the assault rifle when firing, while the installation of the bar did not require factory conditions, but was possible in workshops for all types of assault rifles Kalashnikov.

To solve the problem in the device for mounting the sight on automatic weapons, including a bar for mounting the sight, rigidly mounted on the cover of the receiver of the weapon, and the stabilization unit, rigidly mounted on the front of the cover of the receiver of the weapon, the new is that the stabilization unit is made in in the form of a fork structure covering the block of a standard mechanical weapon sight, a plate overlay is attached to the back of the receiver cover to provide rigid fixation of the cover o in relative box receiver arms having a U-shaped slit set up so that its internal profile repeats the shape of the opening in the lid of the receiver for the heel protrusion guide rod return mechanism.

The invention is illustrated by drawings.

In FIG. 1 shows a General view of the device for mounting the sight: a) - side view, b) - top view; in FIG. 2 - a fragment of a Kalashnikov assault rifle with an installed device for installing a sight; in FIG. 3 - a fragment of a Kalashnikov assault rifle with mounted sight and folded butt.

A device for mounting a sight on a weapon includes a standard receiver cover 1, onto which the bar 2 is rigidly mounted using rivets 3 for mounting the sight. In the front part of the lid, a stabilization unit 5 having a forked shape is rigidly fixed with four rivets 4. In the rear part, the lid 1 is equipped with a plate-like lining 6, which has a U-shape and is fixed upward with the help of rivets 7, while its profile repeats the shape of the hole 8 on the receiver cover for the protrusion of the heel 9 (Fig. 2), the return guide rod mechanism (not shown), when the cover 1 is mounted on the machine, the fork element 4 covers the block 10 of the standard mechanical sight 11 of the machine. From FIG. 3 shows that the proposed device

- 1 014931 for mounting a sight on a standard Kalashnikov assault rifle with a folding butt does not interfere with folding the butt of the assault rifle in a regular fixed traveling position.

The device operates as follows. The regular cover 1 of the receiver is removed from the machine, on top of it in the middle part with the help of two rivets 3 is installed a strap 2 for mounting the sight, in the front of the cover with the help of four rivets 4 a stabilization unit 5 of the fork structure is installed, in the back of the cover with four rivets 7 is installed plate lining 6 U-shaped. Then, the modified receiver cover is put into a standard position on the machine so that the forked protrusions on the stabilization unit 5 grab the block 10 of the standard mechanical sight 11 of the machine, while the heel 9 of the return mechanism is clearly fixed in a reinforced hole 8 of a rectangular shape, formed together by a plate plate 6 and regular hole in the cover. Next, a sight of any class (telescopic, collimator, night, laser) is installed on the bar, which has a bottom guide for installation on the bar Ρί sabine. Moreover, all of these operations can be performed in the conditions of army workshops.

The tests fully confirmed the high stability of the battle of the AKS-74 assault rifle with the PK-01 VP collimator sight. After 3000 rounds with 300 cycles of removal and subsequent installation of the receiver cover with a mounted sight (which fully corresponds to the simulation of combat training of weapons), the midpoint hit was less than 5 cm at a distance of 100 m (less than 2 arc minutes). Moreover, the adjustment of the sight for all 3000 shots was absolutely not carried out.

The device has ease of installation, stability of the axis of the sight relative to the axis of the barrel of the machine gun, the possibility of a wide range of adjustment of the optical sight relative to the shooter, a clear and reliable fixation to the weapon without the use of a special tool. This design provides the ability to conduct targeted shooting at a target without removing the collimator sight through the aperture of the latter, using a standard mechanical sight.
