Description

The utility model relates to defense technology, in particular to anti-personnel under-barrel grenade launchers.

Known 40 mm grenade launcher GP-25 (see g. "Shotgun. Weapons and ammunition. No. 2/1997, p. 20-26), containing a barrel, a housing with a breech, bracket. The bracket consists of front and rear supports, which cover the gas chamber and the ring of the forearm of the machine. A compensator is installed on the front support of the bracket, the upper feather of which is placed in the groove intended to accommodate the ramrod, between the two female segments of the cylindrical surface of the front bracket support, the lower feather installed in the groove flush with the lower plane of the bracket is pressed by the barrel during assembly. The rear bracket support has a groove between two base segments of the cylindrical surface in which the ramrod is located. When installing the grenade launcher on the machine, the upper feather of the compensator draws in the ramrod installed under the barrel of the machine and fixed in the socket of the fly block.

The disadvantage of the GP-25 grenade launcher is:

- the possibility of inertial displacement of the ramrod in the exit zone of the grenade, due to the failure to ensure reliable fixation of the ramrod in the socket of the machine’s front sight when fired from a grenade launcher, which leads to an unpredictable change in the flight path of the grenade and a decrease in the safety of firing from the grenade launcher.

The closest analogue is an under-barrel grenade launcher for a full-time submachine gun (RF patent No. 2117897, June 4, 1997 for the invention “An under-barrel grenade launcher, F41C 27/06) containing a barrel, an arm with front and rear supports covering the gas chamber and the ring of the forearm of the machine, in which holes are made to accommodate the ramrod. A ramrod clamp is installed in the front block of the front sight, which is fixed in the ramrod hole and prevents the ramrod from shifting when firing from a grenade launcher.

The disadvantage of a grenade launcher is:

- the possibility of improper assembly of the grenade launcher with a submachine gun, which leads to an inertial displacement of the ramrod from the locking slot of the submachine gun into the exit zone of the grenade, since not setting the ramrod lock does not exclude the possibility of firing from the grenade launcher attached to the submachine gun, and leads to an unpredictable change in the grenade's flight path and a decrease safety firing from a grenade launcher.

The objective of the utility model is the creation of a grenade launcher to a standard machine gun, providing a technical result consisting in ensuring the safety of firing from a grenade launcher attached to the machine gun.

This technical result in an under-barrel grenade launcher to a standard machine gun containing a barrel, an arm with front and rear supports covering the gas chamber and the forearm ring of the machine, in which holes are made to accommodate the ramrod, is achieved by the fact that the supports or one of the bracket supports are made with the possibility of overlapping holes to accommodate the ramrod.

In this case, the front bracket support overlaps the hole in the gas chamber to accommodate the ramrod.

Also, the rear bracket support overlaps the hole in the forend ring to accommodate the ramrod.

In addition, the front and rear supports of the bracket overlap the holes for placing the ramrod in the gas chamber and forearm ring.

Installation of a grenade launcher on a machine gun is possible only after removing the ramrod from under the barrel of the machine, which eliminates the ramrod blocking the grenade launch area during firing and ensures the safety of firing from the grenade launcher. To clean the barrel of the machine gun, a composite ramrod from the set of accessories for the grenade launcher is used.

The essence of the utility model is illustrated by drawings, where in FIG. 1 shows a General view of the grenade launcher mounted on the machine; in FIG. 2 is a section AA in FIG. 1 (the front bracket support blocks the hole in the gas chamber to accommodate the ramrod); in FIG. 3 is a section BB in FIG. 1 (the rear bracket support overlaps the hole in the forend ring to accommodate the ramrod).

The under-barrel grenade launcher for a standard automatic machine consists of a barrel 1, a housing 2 with a breech 3, an arm 4. The arm 4 includes a front support 5 and a rear support 6. The front support 5 covers a gas chamber 7, in which an opening 8 is provided for accommodating the ramrod. The rear support 6 covers the forearm ring 9, in which a hole 10 is made to accommodate the ramrod. The seats of the front support 5 and rear support 6 have segments 11 of cylindrical shape, mating with the surfaces of the barrel 12 of the machine, which excludes the possibility of installing a grenade launcher on the machine with a ramrod located under the barrel of the machine.

Installation grenade launcher as follows. When installing the grenade launcher on the machine with a ramrod located under the barrel 12, the segments 11 of the front support 5 and the rear support 6 of the bracket 4 abut against the ramrod and do not allow the seats of the grenade launcher and the machine to be combined, which eliminates the fixation of the grenade launcher. With the ramrod removed, the segments 11 of the front support 5 and the rear support 6 of the bracket 4 are aligned with the counter surfaces of the barrel 12, and with a longitudinal movement backwards, the grenade launcher is fixed on the machine.

Thus, the proposed design of a grenade launcher to a full-time machine ensures the safety of firing from a grenade launcher attached to the machine.
