Central Bureau of Sports and Hunting Weapons, Russia), which includes a frame, a handle, a barrel with a magazine, a shutter, firing pin, mainspring, trigger, trigger and aiming devices. 70 Disadvantages of this gun: - the possibility of "micro-barrels" (downward movement of the gun barrel in the vertical plane) when firing; - insufficient length of the barrel to ensure high indicators of compactness and accuracy.

The closest analogue of the invention is the accepted target small-caliber 5.bmm single-shot Olneva pistol (Patent of Ukraine Мо37494 МПК Р41сС 3/00 according to the application Мо99041826 dated 01.04.1999), which contains a frame, a handle, a 72 barrel with a magazine, a striker, a striker, a mainspring, a trigger grappling hook, reloading handle and aiming devices. Disadvantages of this gun: - the possibility of "micro-bumps" - oscillations of the gun in the vertical plane downwards when fired, caused by the large compression force of the mainspring, which provides an impact on the butt at an angle; - insufficient length of the barrel to ensure high indicators of compactness and accuracy.

The basis of the invention is the task of creating a gun in which, by changing the compositional structure, it is possible to eliminate "micro-bumps", as well as to significantly increase the initial speed of the bullet, indicators of mass and accuracy of shooting.

The task is solved by the fact that a new design of the target small-caliber 5.bmm single-charge pistol "Artefact" Olnev (hereinafter, the pistol) has been developed, which includes a frame, a handle, a barrel, a trigger hook, a reloading handle, a cup-shaped combat larva with a loading window and ejecting Ge) of the fired cartridge case, and a through-groove for the striker, a spring-loaded ejector, which enters with a tooth into the edge of the cartridge case of the ring ignition, a reflector located in the blind groove of the warhead, the striker, which passes through the through-groove of the warhead and is installed in the bore of the barrel so that its sharp end protrudes into the breech section of the barrel in the direction of the edge of the charge of the ring ignition, the striker, covered by the mainspring and located in front of the striker, the trigger and the aiming devices, and the barrel is immovably fixed to the frame, its length is significantly increased due to the fact that that the rear part of the barrel is bent with a large radius and is located in the handle, combat the larva covers the breech part of the barrel, is installed with the possibility of sliding on the outer surface of the barrel and is fixed in the most forward position by a spring-loaded reload handle, and the striker and striker are located on the same axis inside the handle, the striker is made with a semicircular head, the shoulder tooth clings to its protrusion of a spring-loaded sear mounted with - the possibility of rotation around the axis, while the second arm of the sear is pressed by a plate spring to the trigger, in addition, under the semicircular head of the striker there is also a shoulder of the trigger, fixed on the axis with the possibility of rotation, and the second arm of the trigger is connected to traction with a combat larva. "

The length of the barrel of the proposed pistol, bent with a large radius in the rear part of the barrel, reaches 520 mm, and Z exceeds the length of the pistol, which is equal to 480 mm, which explains the extraordinary name of the pistol with "Artifact". The action of the comparison, the length of the barrel of the MC-2 pistol is 290mm, the target small-caliber 5.bmm

"Iz" Olneva single-shot pistol (patent of Ukraine Mo37494 MPK Р41С 3/00| has a barrel length of 432mm with a gun length of 516bmm.

On the curved section of the barrel, the speed of the bullet increases from O to 120 m/s, and on the straight section

The speed of the bullet reaches its maximum value, namely 320Ω/s at the muzzle, which stabilizes the trajectory and flight of the bullet outside the barrel, and significantly increases the accuracy and accuracy of shooting, bringing these indicators closer to

Gee! level of small-caliber rifles. In addition, the curvature of the barrel made it possible to place the firing pin and striker on almost the same axis, which made it possible to reduce the stiffness of the mainspring by approximately 3095, while the "micro-bits" are practically absent.
