Known release site firing mechanism self-loading small arms on a "bullpup" on the basis of AK (RF patent for useful model No. 8790 from 26.09.1997,), in which the kinematic connection of the base or standard trigger AK with additional trigger arm fire control on a "bullpup" made in the form of non-separable longitudinal Z-shaped thrust inside of the receiver to the right of the store, that is to the right of the vertical plane passing through the longitudinal axis of the weapon, in this case, transmission of motion from the traction to rotate the base trigger implemented due to the pressure element is mounted on the axis of the base and the trigger. The disadvantages of this firing site firing mechanism for guns on a "bullpup" on the basis of AK are: - inability to use this construction the trigger node in automatic weapons on a "bullpup" on the basis of the AK, as on the right (where should accommodate thrust) is part of the regular trigger - timer; - increased likelihood of dirt, dust the precipitation cravings trigger node through the cutout in the receiver cover when firing due to its location on the right side inside the receiver, what is a negative factor for the smooth operation of the trigger node; - rod is pressed against the bottom of the receiver, which increases friction and makes the descent tight. Describes the trigger node to trigger mechanisms weapons on a "bullpup" on the basis of AK is the closest to the technical essence and the achieved technical result. The technical effect expected from the use of the invention is to improve comfort (stress reduction descent) and the reliability of the release site for the firing mechanism of the weapon on a "bullpup" on the basis of the AK while ensuring the possibility of its use in semi-automatic and automatic weapons, which is achieved due to the new layout of the trigger node inside the receiver and simplifying its construction. Thus, the technical result expected from implementation of the invention is an expansion of the functionality of the trigger due to the possibility of its use with the kit of parts, providing a rapid transition from traditional layouts to the layout of the "bullpup", while improving comfort, reliability, and accuracy. The above problem is solved in the release site, which has the following combination of characteristics: - trigger;</> - longitudinal Z-shaped rods placed along the left inner side of the receiver, one end connected to the trigger arm fire control, and the other with adapter mounted on the axis of the regular trigger firing mechanism, or directly with the standard trigger, modified additional hole or transverse axis under the toe thrust; adapter, made for example in the form of rails from the outer side of curved ledge regular trigger, is provided in the lower part of the hole axis regular hook, and in the upper - bracket, covering the standard trigger under shaped protrusion from the back and inner lateral sides, and a transverse axis under the toe of the longitudinal thrust. New signs proposed firing site firing mechanism of the weapon on a "bullpup" on the basis of AK are: - placing the longitudinal Z-shaped thrust along the left (relative to the vertical plane passing through the longitudinal axis of the weapon) the inner side of the receiver; - performance adapter standard trigger firing mechanism in the form of rails from the outer side of curved protrusion, provided in the upper part of the bracket covering the standard trigger under curly ledge ssdna and inner lateral sides, and the transverse axis under the toe of the thrust. Thus, the proposed release site for the firing mechanism of the weapon on a "bullpup", containing the trigger on a "bullpup", connected by a longitudinal thrust inside of the receiver, with the standard trigger, wherein the rod is made of Z-shaped and placed to the left of the vertical plane passing through the longitudinal axis of the weapon under the power jumper and above the axis of the timer and the axis of the trigger of the receiver. When this trigger node may optionally be provided with an adapter in the form of pads installed with the outer side of the curved protrusion of the regular trigger, made in the upper part of the bracket covering the standard trigger under shaped protrusion from the back and inner lateral sides, and a transverse axis under the toe of the thrust. In addition, the trigger node can additionally be equipped with an adapter, in the form of pads installed with the outer side of the regular trigger, made in the lower part with a tooth within a groove made on a rectangular protrusion of the regular trigger, and with a transverse axis under the toe of the thrust. At the same time, the trigger can be executed with the axis to toe thrust or hole axis thrust on figure ledge. And, Nakane is, the standard trigger is made with a hole on the curved ledge under transverse axis fixed on the draft. Thus, the rear axle torque can be made as free with the necessary constraints on it, and with threaded or other connection with one of the connected elements, i.e. thrust or trigger. The essence of the proposal is illustrated by figure 1-6, where: - figure 1 shows the AK-74 M with a defined set of elements of the bullpup; - figure 2 presents the AK-74 M in the usual arrangement; - figure 3 a view in isometric layout of traction in the receiver; - 4 shows the adapter mounted on the standard trigger; - figure 5 a view in isometric option 2 attachment to the standard trigger hook; - figure 6 a view in isometric of options 3 and 4 of the attachment to the standard trigger hook.
