Description

 The invention relates to weapons technology and can be used in hunting rifles.

 The IZh-18 hunting single-barrel gun is known (see. Hunting and sporting weapons, Moscow: B / O Raznoeksport, p.15 20).

 The shotgun has a tipping barrel to which a barrel-mounted hook and a hinge stand are soldered, which determines the position of the hinge with the fore-end in the assembled gun and makes it possible to “break” the gun for reloading.

 The hunting rifle "PARONER" (see "Gun Digest", 1990, p. 386), taken as a prototype, contains a "breakable" barrel with a hinge stand and an under-barrel hook, which is attached to the barrel by brazing.

Hunting rifles are used to shoot at a commercial beast, when firing is carried out by a bullet of various types, and with a deliberately powerful charge to achieve a heavy lead bullet of a certain speed and guaranteed lethal force. Under these superheavy operating conditions, the following shortcomings are revealed in well-known guns:
the margin of safety of the barrel tube itself is small and a rupture of the barrel with an arrow injury is possible (which was observed in practice);
soldering the underbarrel hook and the hinge strut does not provide the required bond strength, which also leads to the destruction of the barrel unit;
technology of brazing a thin pipe for solder, i.e. high temperature of soldering, makes local changes in the structure (for example, increase in hardness) of the barrel at the place of soldering, which negatively affects further processing;
the bullet shot of the barrel in terms of accuracy and accuracy is significantly inferior to the shot from the rifled barrel, and the shooter's life often depends on the accuracy of the shot, the sights of famous guns, namely the front sight and the forehead plane are too primitive for accurate shooting.

 The essence of the invention lies in the fact that the barrel unit containing the barrel with a hinge stand and sights, is equipped with a coupling having a groove for a shoulder made on the barrel, and a bar having a tide at the end, made in the form of a hinge stand with a hole in the barrel. In addition, the barrel coupling is made with a groove under the scope mount.

 The invention improves the reliability and safety of handling hunting weapons, and also allows the use of a rifled cartridge in a tipping weapon, as the most powerful, reliable and having the best accuracy and accuracy in comparison with a smooth bullet shot, and therefore improves the ergonomic and combat characteristics of a tipping single-barrel guns. In FIG. 1 shows a general view of a hunting single-barrel rifle with a rifled barrel unit; figure 2 General view of the block rifled barrel; figure 3 section aa in figure 2; figure 4 section BB in figure 2.

 The inventive receiver unit contains a barrel 1 (Fig. 1), pressed into the corresponding holes of the coupling 2, the box 3 and the forearm 4. The clutch 2 (Fig. 2) is equipped with a bar 5 and a tide 6 made in the form of a hinge stand with a hook 7 for the forearm latch and having an opening 8 under the barrel 1. To fix the barrel 1, a groove 9 is made inside the bore diameter of the sleeve 2, and a shoulder 10 is made on the barrel 1. The sleeve 2 reinforces the barrel chamber (similar to a fastened barrel), because it is in this place that maximum pressure develops when fired. On the upper plane of the coupling 2 there is a groove 11 (figure 3) of the "swallow tail" type for installing any existing bracket for the optical sight. On the shelf 12 (figure 2) provides for the installation of any known open sight type "front sight" for open aiming.

 The work of a hunting rifle, as well as all its other elements remain unchanged, i.e. it became possible to supply existing rifles with a rifled block, thereby increasing the applicability of the rifle.
