Benefits of technology

The invention is about ensuring that a firearm's sight alignment remains constant when the barrel is removed from the receiver. To achieve this, the firearm has a receiver and a detachable barrel with a mount for various sight devices. The barrel is fixed to the receiver by a clamp with a longitudinal groove. The sight base is fixed to the barrel and positioned in the groove. The clamping bolts secure the attachment either directly to the barrel or to the sight base. In an optional variation, the bolts pass through holes in the sight base and are tightened with nuts or other parts, including thread. In another optional variation, the barrel is fixed in the receiver by a union nut screwed onto a protruding section of the barrel attachment unit in the receiver.

Problems solved by technology

All known prior art solutions for clamping the barrel in the receiver, such as the patent RU 2303227 C1, F41C 7 / 00 (2006 January), F41A 21 / 48 (2006 January), do not allow for sighting devices to be installed directly on the breech section of the barrel, which results in a loss of the registered mean bullet impact point upon removal of the barrel from the firearm receiver and its subsequent reinstallation.

Embodiment Construction

[0020]The firearm with a detachable barrel (FIG. 1) includes a barrel 1, a sight base 2 rigidly fixed on the barrel, and a receiver 3.

[0021]The barrel 1 is installed in the barrel attachment unit 4 (FIG. 3) of the receiver 3 and fixed in place by the clamping bolts 5. As the bolts 5 are tightened in the sight base 2, the barrel 1 is fixed in the barrel attachment unit 4 of the receiver 3 (FIG. 3, FIG. 4).

[0022]In an optional variant, the barrel 1 (FIG. 5) is fixed in the barrel attachment unit 4 of the receiver 3 by the bolts 6 screwed directly into the barrel walls.

[0023]In an optional variant, the barrel 1 (FIG. 8) is fixed in barrel attachment unit by the clamping bolts 7 pass through holes in the sight base and tightened with the nuts 8 or other parts comprising thread.

[0024]In an optional variant, the barrel 1 (FIG. 9, FIG. 10) is fixed by the union nut 9 screwed on to the protruding barrel attachment unit 4.2 of the receiver 3.2.

Abstract

The invention relates to small firearms and constitutes a device for attaching a barrel to the receiver. A clamping attachment of the barrel to the receiver allows for various sighting devices to be installed directly on the breech section of the barrel, thus allowing the barrel to be detached from the firearm without losing the alignment of the sight against the barrel.

Description

TECHNICAL FIELD[0001]The invention related to the field of weapons and may be utilized in firearms with detachable barrel.BACKGROUND OF THE INVENTION[0002]All known prior art solutions for clamping the barrel in the receiver, such as the patent RU 2303227 C1, F41C 7 / 00 (2006 January), F41A 21 / 48 (2006 January), do not allow for sighting devices to be installed directly on the breech section of the barrel, which results in a loss of the registered mean bullet impact point upon removal of the barrel from the firearm receiver and its subsequent reinstallation.DISCLOSURE OF INVENTION[0003]The proposed invention addresses the problem of ensuring the preservation of sight alignment constantly relatively the barrel upon detachment of the barrel from the receiver.[0004]To achieve the said technical objective, the firearm comprising a receiver and a detachable barrel with a mount for various sighting devices, brackets and other attachments (hereinafter referred to as the “sight base”) fixed ...
