Abstract

FIELD: weapons and ammunition.

SUBSTANCE: small arms with optical sight comprises a receiver with a barrel, on which using the connection "dovetail" the bracket is fixed for mounting an optical sight, consisting of a base and the cantilever arm in the form of a Picatinny rail, on the front part of the receiver a ledge two openings is made, aligned along the bore, and on the cantilever arm of the bracket at the bottom a joggle is made, on which two pins are located, interacting with the openings at the mounting bracket to the arm. The ledge with the openings can be made on the stud available on the receiver for the passage of the gas tube, and at the top it has a recess for providing the ability of aiming. The base of the bracket has a box shape, in the bottom of the base the windows are made, between which the base lock is located, and on the rear side wall of the base there is a ledge which abuts the rear end of the joggle located on the receiver.

EFFECT: design enables to remove and install quickly the necessary equipment, enables to fix securely the front cantilever arm and the base of the bracket, is a light and rigid structure and thus eliminates the movement and elastic deformation of the bracket.

Description

The invention relates to the field of small arms, in particular to weapons that are used by special forces of law enforcement agencies.

Currently, various types of small arms with an optical sight are known, using various methods of securing sights. In modern conditions of warfare, one of the main requirements for small arms is the stability of maintaining a constant position of the mid-point of impact. Known types of weapons, as a rule, do not satisfy such a requirement, since it does not ensure the preservation of the unchanged position of the sight on the weapon during firing and after removal - setting during disassembly of the weapon.

The closest in technical essence to the claimed weapon is the design of the weapon according to the utility model patent of the Russian Federation No. 40459, F41G 1/38, 09/10/2004, containing a receiver with a seat for quick installation of the bracket for a removable sight using the dovetail connection ”Consisting of a base and a back support. At the same time, both in the front and in the rear part the bracket is attached using the dovetail joint. The mount has an eccentric with a lever in the front to secure the device to the base.

The manufacture of such a device causes difficulties in manufacturing.

When shooting from such a weapon, displacement of the bracket with the sight is inevitable, which means that it does not have high accuracy and accuracy of fire. In addition, this design does not allow to install on a weapon simultaneously (tandem) a collimator sight and a night vision monocular.

The objective of the invention is to create a weapon with a quick detachable sight that has high accuracy and accuracy of fire and allows you to place on it simultaneously with an optical sight other necessary equipment, for example a collimator sight, a monocular for night vision.

The problem is solved as follows.

In a small arms with an optical sight, containing a receiver with a barrel, on which, using the dovetail connection, a bracket for mounting an optical sight is fixed, consisting of a base and a console part in the form of a Picatinny rail, a protrusion is made on the front of the receiver two holes coaxial to the bore of the barrel, and on the cantilever part of the bracket from below, a reciprocal protrusion is made, on which two pins are placed, interacting with the holes when the bracket is mounted on the weapon.

The protrusion with holes can be performed on the tide, available on the receiver for the passage of the gas tube, and on top has a recess for enabling aiming.

The base of the bracket has a box-shaped shape, windows are made in the bottom of the base, between which there is a base lock, and on the rear side wall of the base there is a protrusion abutting against the rear end of the reciprocal protrusion located on the receiver.

The proposed design allows you to quickly remove and install the necessary equipment, allows you to securely fix the front cantilever and the base of the bracket, is a light and rigid design and thereby eliminates the movement and elastic deformation of the bracket. Such weapons have high accuracy and accuracy of fire and a stable point of impact.

An example implementation of the claimed invention is presented in the drawings.

Figure 1 - General view of the weapon.

Figure 2 - receiver with a seat.

Figure 3 - quick-release bracket.

Figure 4 - attachment of the bracket to the receiver.

The weapon contains a receiver with a barrel assembly 1, butt 2, magazine 3. On the side surface of the receiver there are standard dovetail protrusions 4 (FIG. 2) designed to mount standard optical and night sights. An arm 5 is also mounted on these projections.

On the front of the receiver there is a tide 6 with a hole 7 for a gas pipe. A protrusion 8 is formed on the upper part of this tide 6, in which two holes 9 are formed, coaxial with the bore. The protrusion 8 on top has a recess for enabling aiming.

The bracket 5 (figure 3) consists of a base having a dovetail profile, interacting when installed with the tabs 4 on the receiver, and the console part 10, made in the form of Picatinny rail. On the back wall of the base of the bracket there is a protrusion 11, abutting against the last protrusion 4 on the receiver when installing the bracket. On the cantilever part of the bracket, there is a protrusion 12 below, in which two pins 13 are inserted coaxially to the bore, which enter the holes 9 when the bracket is installed. In addition, the base of the bracket has a box shape, in the bottom of the base there are windows, between which there is a base lock 14, which is made, for example, in the form of a lead screw with a screw.

To install the bracket on the weapon, it is necessary to combine the front part of its base with the protrusions on the receiver and, moving the bracket forward along the weapon, insert the pins 13 into the holes 9. For the final fixation of the bracket on the receiver use the latch 14. When fired, the bracket with optics mounted on it tends to move forward, but this is prevented by the protrusions 11 and 12, which subsequently improves the accuracy and accuracy of fire.
