Abstract
The invention relates to a firearm and is a device for attaching the barrel to the receiver, for which the breech attachment unit is made in the form of a compressible clamp connection, the slot of which is located in the upper part of the receiver, and the upper part of the receiver itself allows to install and fix the sights on it.
Claims
1. Receiver of the firearm, characterized in that the attachment unit of the barrel's breech is made in the form of a compressible clamp connection, the slot of which is located in the upper part of the receiver, while the upper part of the receiver is the basis for installing and fixing the sights.
2. Receiver according to claim 1, characterized in that the number of parts compressing the clamp connection is two or more pieces.
Description

[0006] The essence of the invention is explained by sketches, where:
[0007] on FIG. 1—shows the external and axonometric views of the receiver with the installed barrel and sight; the diagram of the installation and fixation of the barrel in the receiver; installation of the sight;
[0008] on FIG. 2—shows the appearance of the receiver, sections A-A, B-B;
[0009] on FIG. 3—shows the appearance of the receiver with the installed barrel and sight; sections C-C, F-F, local view D;
[0010] on FIG. 4—shows the appearance of the receiver with the number of tightened parts, which is more than two, sections V-V, S-S;
[0011] on FIG. 5—shows the appearance of the receiver with the installed barrel, when the receiver has two or more compression parts, an axonometric view, a diagram of the installation and fixation of the barrel in the receiver.
IMPLEMENTATION OF THE INVENTION
[0012] Receiver 2 (FIG. 1, 2, 3) for attaching the breech 1.1 of the barrel 1 (FIG. 1) contains an attachment unit 3 (FIG. 2, 3), the breech of the barrel 1.1 (FIG. 1), which is a compressible clamp connection,
[0013] including the channel 3.1 (FIG. 2), a longitudinal slot T (FIG. 2, 3), made on the compressible section 3.2 (FIG. 2, 3) of the upper part 2.1 (FIG. 2, 3) of the receiver 2 (FIG. 2), while the upper part 2.1 allows to install and fix the sights 18 (FIG. 1, 3).
[0014] Barrel 1 (fig.1) is placing with its breech 1.1 (fig.1,3), according to the diagram in FIG. 1 in to the channel 3.1 (FIG. 2, 3). Further occurs the compression of the compressible part 3.2 (FIG. 2, 3) with the help of part 11 (FIG. 1, 3), passing through the hole 3.3 (FIG. 2), while the slot T does not close.
[0015] A variant of the receiver 4 (FIG. 4, 5), when the number of parts compressing the clamp connection is two or more pieces, has an attachment unit 5 (FIG. 4) of the breech 1.1 of the barrel 1 (FIG. 5), similar in structure to the unit 3 (FIG. 2, 3), except that there are two or more transverse holes 3.3 (FIG. 4).
