Abstract

FIELD: weapons and ammo.

SUBSTANCE: invention refers to the military area, particularly, to the mounting bracket for auxiliaries of the Kalashnikov assault rifle. The bracket contains two pivotally interconnected halves forming the longitudinal hole for the barrel when combined. The halves are screwed above the barrel, while lateral and bottom parts of the halves are performed in the form of projections with Picatinny rails. The top part of a bracket half is performed in the form of a sector corresponding by dimensions to the radiuses of the gas cylinder and gas cylinder tube of the Kalashnikov assault rifle. The projections with Picatinny rails have air holes, and there are holes for gas discharge from the gas cylinder, as well as the mounting of auxiliaries without clips for Picatinny rails, on the lateral surfaces of the bracket halves.

EFFECT: mounting bracket for auxiliaries of the Kalashnikov assault rifle possesses high repeatability, effective heat sink, possibility to install devices on it that have no clips for Picatinny rails.

Description

Known bracket M 063 (www.dx.com/p/universal-aluminum-alloy-weaver-stile-quad-rail-barrel-mount-w-hex-wrench-156529#.Vq2d8u-gM61). The bracket is made of two parts, pulled together by four screws. In a connected form between the parts, a longitudinal hole of square cross section is formed for the barrel of the weapon, and on the four lateral protrusions there are Picatinny rails (Weaver) for installing lights, bipods, handles, laser target designators (LCC) and other auxiliary equipment on them. The bracket is mounted on a cylindrical section of the barrel of the weapon and does not have a radial fixation for the structural elements of the weapon.

The disadvantages of this bracket are the lack of quick release, reproducibility of the installation due to the lack of fixing elements in a certain position on the cylindrical barrel and the inability to install auxiliary devices on it that do not have clamps for Picatinny rails.

Known bracket G&G TRI-RAIL BARREL MOUNT G-03-127 (http://www.guay2.com/web/part/rail/rail_3.php?lang=en) for installing accessories on the M16 rifle. The bracket is made of two pivotally connected parts, forming a longitudinal round channel for clamping a cylindrical section of the barrel, and a groove for fixing the bracket in a certain position on the base of the M16 front sight (http://strikeup.ru/uploads/images/00/08/38 (2013/11/14/28d761.view.tif). Details are pulled together by one screw. On the bracket there are 3 protrusions along the axis, made in the form of Picatinny rails (Weaver).

The disadvantages of the bracket “G-03-127” are the impossibility of its reproducible installation on Kalashnikov assault rifles, strong heating during firing and the impossibility of installing auxiliary devices on it that do not have clamps for Picatinny rails.

The objective of the invention is the creation of a bracket for mounting auxiliary devices on Kalashnikov assault rifles with high reproducibility of the installation, good heat dissipation and the ability to install devices on it that do not have clamps for Picatinny rails.

The task is achieved in that the bracket for mounting auxiliary devices on Kalashnikovs contains two articulated halves, when folded, form a longitudinal hole for the barrel, over which the halves of the bracket are pulled together by one screw, and the side and lower parts of the halves of the bracket are made in the form of protrusions with Picatinny rail, with the upper part of the halves of the bracket made in the form of a sector, the size corresponding to the radii of the gas chamber and the front of the gas tube AK, the distance between the lower surface of the sector and the upper part of the hole for the barrel corresponds to the gap between the upper surface of the barrel and the lower surface of the AK gas chamber, the protrusions with Picatinny rails have ventilation holes for cooling the strips, and on the side surfaces of the bracket halves there are openings for venting gases from the gas chamber and mounting accessories that do not have clips for mounting on Picatinny rail.

The invention is illustrated by drawings.

The bracket for attaching auxiliary devices to Kalashnikovs (1) contains: left (2) and right (3) halves connected in the lower part by a hinge (4) (Figure 1). Halves (2) and (3) are pulled together by a screw (5). On the side walls of halves (2) and (3) there are protrusions (6, 7), the ends of which are made in the form of Picatinny rail (8, 9), the lower ends of the halves (2, 3) also form a ledge (10) with Picatinny rail ( 11), in which the hinge (4) is located. Inside the protrusions (6, 7, 10) there are ventilation holes (12, 13, 14). Also on the side surface of the right (3) half there is an opening (15) for the connecting screw (5), and symmetrically to it, on the left (2) half there is a threaded hole (16) for the screw (5) (Figure 1, Figure 2 , Fig. 5).

When folding, half (2, 3) form an opening (17) for clamping the AK barrel with a size corresponding to the section of the barrel under the AK gas chamber.

The upper part of the bracket (1) is made in the form of a sector (18) with two radii R1 and R2 corresponding to: R1 is the radius of the outer side surface of the AK gas chamber; R2- slightly increased radius of the front end of the AK gas tube. The distance between the upper part of the hole (17) and the lower part of sector R1 A – B (FIG. 3; FIG. 4) corresponds to the distance between the lower surface of the gas chamber and the upper surface of the barrel AK below it. According to the length of sector (18), section C-D corresponds to R1, and section D-F to R2 (Figure 3).

On the side surface of the halves (2, 3) there are also holes (19) for venting gases from the gas chamber AK and holes (20) for mounting equipment that does not have clamps for Picatinny rails (Figure 2, Figure 3).

Install bracket (1) on the AK.

The bracket is installed between the barrel and the AK gas chamber by clamping one screw using a standard screwdriver, without disassembling the machine.

Unscrew the screw (5) from the hole (16), part the halves (2, 3) to the sides on the hinges (4) (Figure 4). Place halves (2, 3) of the bracket (1) on the portion of the AK barrel under the gas chamber so that the hole (15) is on the right side, and the section C-D of sector (18) with R1 is adjacent to the gas chamber (section with R2 DF it is located under the front lower surface of the gas tube AK, without touching it). A screw (5) is inserted into the hole (15) and the halves (2, 3) are pulled together with a screw (5) in the threaded hole (16). In this case, the sector (18) and the halves of the hole (17) squeeze the barrel and the lower side surface of the gas chamber AK, firmly securing in a strictly defined position (Fig.6), without the possibility of radial and axial displacement.

The bracket (1) works as follows: after installing the bracket on the AK, auxiliary equipment is installed on its side brackets (8, 9) and lower (11): laser target designator (LC), flashlight, bipod, handles. The LCC is brought to normal combat using a machine gun’s mechanical sight and is used to quickly bring optical sights to normal combat or for target designation in the dark.

To install equipment that does not have clamps under the Picatinny rail on the bracket, for example, upper brackets, holes (20) are used (Fig. 7).

To remove the bracket from the AK, unscrew the screw (5), spread the halves (2, 3) and remove the bracket from the AK. When re-installing the bracket on the AK, it is installed reproducibly, bursting between the gas chamber and the barrel, as between two cylinders, which ensures that the position of the laser beam is constant relative to the optical line of the AK mechanical sight at fixed distances.

The ventilation openings (12, 13, 14) provide a good heat sink guaranteeing the safe installation of auxiliary devices with plastic fasteners on the bracket, which eliminates their fusion during intense shooting from heating the bracket from the barrel.
