Dummy assault rifle

Abstract

Converting a functioning assault rifle to an inoperative dummy gun suitable for collectors by replacing the receiver with a receiver filled with a solid material. The filled spaces of the receiver prevent the cooperative operation with the other components of the gun. The dummy receiver is externally indistinguishable from the functioning receiver. Thus, a model rifle is converted for collectors so as to be unrecognizable from the functioning gun. To accommodate the filled spaces in the receiver, the lower part of the cooperating bolt carrier is milled off. The dummy receiver may include an affixed rear sight base.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority under 35 U.S.C. § 119 of Czech Patent Application No. PV 2004-637, filed on May 21, 2004, the disclosure of which is expressly incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to the conversion of a weapon into a dummy gun suitable for collectors. In particular, a model Sa vz. 58 assault rifle can be converted using the principles and apparatus of this invention. [0004] 2. Discussion of Background Information [0005] Generally, when converting to a dummy gun, it is necessary to ensure, in accordance with the law, that it is impossible to load and shoot the weapon. Typically, this is done by ensuring that the loading and shooting parts are impossible to separate from one another and also that their mutual movement is prevented. This is usually achieved by plugging the barrel in the cartridge chamber with a ste...

AI Technical Summary

Benefits of technology

[0008] By replacing specific parts of a rifle with modified non-operative elements, whose external appearance is the same as the originals, the appearance of the gun is maintained while preventing its operation.

[0009] Specifically, the above described drawbacks in producing a dummy rifle such as the Sa vz. 58, are eliminated by replacing the original receiver with a dummy receiver that is made in the shape of the original receiver. The dummy receiver is made as a solid unit, in such a way that in the place where the cartridge would be inserted into the chamber, where the cartridge would be pushed from the magazine into the area in front of the chamber, in the place where the bolt and the locking piece would move, and in the place of the rear part of the trigger mechanism, the receiver is left without any holes, openings or spaces. Further, the bottom of the bolt carrier is milled off up to the middle of the firing pin hole diameter.

[0010] In one embodiment of the present invention, the dummy receiver includes an attached rear sight base and replaces the existing receiver and sight together. Alternatively, the existing rear sight base can be first attached to the barrel and then cut free from the operative receiver, enabling the use of a dummy receiver without a rear sight.

[0011] A dummy gun produced in this way is externally indistinguishable from the original functioning weapon, yet it cannot be converted into a functioning gun. The solid receiver prevents the movements of the remaining operative parts. Additionally, the dummy receiver can be made of a soft material, e.g., aluminum, plastic etc., that would not withstand use as an actual weapon.

[0013] According to the invention, there is provided a dummy receiver for disabling an operative gun while maintaining its external appearance, the gun including a functioning receiver, a cartridge magazine, a trigger mechanism with a firing pin, and a barrel. The dummy receiver comprises an elongated receiver, sized and shaped to correspond to the functioning receiver and cooperating with the functioning magazine and trigger mechanism. The elongated receiver includes a solid material filling the space where the cartridge would be received from the magazine in an operative receiver, whereby, the dummy receiver, by replacing the functioning receiver, prevents the operation of the gun.
