hzg small submachine gun

Abstract

The gun is designed to offset the impact force of the firing pin during the re-entry process, so that the gun can only be fired after it is fully inserted into the bore. It is a semi-free bolt. Heart-feeding type, from the design point of view, in order to shorten the length of the gun, the magazine is inserted from the grip, and the recoil spring is set under the front barrel. The bullet fired by the gun is a specially designed 8.3mm×25mm single-hole Boxer-style submachine gun bullet. The main feature of this type of bullet is that there is a stable hole in the bullet to stabilize the flight of the bullet. There are two models, one is pointed warhead type, the other is oval warhead shape, the mouth of the barrel is processed with threads to facilitate the installation of the silencer, the buttstock of this gun can be folded and disassembled, and the magazines provided are: Two types, one is a long magazine with no less than 30 rounds, and the other is a short magazine with no less than 20 rounds. The unique shape of the gun is like a large-scale pistol, but it is much shorter than a conventional submachine gun and is easy to carry.

Description

(1) Technical field [0001] The patent of the present invention relates to the field of light weapon manufacturing technology, specifically reducing the weight and size of weapons, increasing the killing range and accuracy, and improving mobility are a new technical design scheme for firearms. (2) Background technology [0002] Since history, most submachine guns have adopted the front-impact inertial lock. The advantage of this design is that it is simple in structure, easy to process, high in maneuverability and reliability, and can be used in various environments. Secondly, it is small in size and easy to carry around secretly. Submachine guns generally use continuous shooting, so the temperature inside the chamber is very high. Because the front impact firing mechanism fails to enter the chamber before firing, it is inclined at the mouth of the magazine and the chamber, which reduces accidental misfires due to overheating of the chamber, but the free bolt moves forward. ...

AI Technical Summary

Problems solved by technology

Because the front impact firing mechanism fails to enter the chamber before firing, it is inclined at the mouth of the magazine and the chamber, which reduces accidental misfires due to overheating of the chamber, but the free bolt moves forward. The poor accuracy of impact-fired submachine guns can easily cause premature fire and shell explosion

Secondly, most submachine guns have small size, insufficient propellant, short bullets, and poor flight stability, which is not conducive to precise killing
