Problems solved by technology

When the bolt is located behind the hammer, the hammer may be released, and the bolt assembly cannot return normally due to the blockage of the hammer, resulting in failure, which affects the reliability of automatic weapons.

Embodiment Construction

[0093] like figure 1 As shown, a light-duty low-recoil automatic weapon includes an upper receiver 1 on which a lower receiver 2, a barrel sleeve 42, a base 20, a mechanical sight 81, and a front sight 82; has a barrel 41;

[0094] Air guiding device 56 is installed on the gun barrel 41; Piston 43, piston spring 83 are installed on the gas guiding device 56, and piston 43 can reciprocate; The maximum backward stroke of frame 3 is greater than its maximum recoil stroke, and the upper receiver 1 will not be hit during the recoil process;

[0095] The firing mechanism frame 5 is installed inside the upper casing 1; the lower casing 2 is equipped with a speed switch 22, a trigger 26, a trigger spring 27, a magazine 46, and the trigger 26 is installed on the lower casing 2 through the shaft 51 and the shaft 52, and It can move back and forth; the trigger spring 27 has a preload on the trigger 26;

[0096] The lever 11 is installed on the base 20 through the lever shaft 55; the r...

Abstract

The invention discloses a light automatic weapon with low recoil, and relates to light automatic weapons, in particular to automatic rifles, light machine guns and automatic shotguns. The light automatic weapon with low recoil is characterized in that the length of the part, on the rearward side of the locking surface of a bolt, of a bolt frame is reduced while increasement of the length of a cartridge receiver is reduced, so that the portability and controllability are improved while recoil is reduced. A hammer is placed on the upper part of the weapon so that the length of the contact part between the hammer and the bolt frame is greater than the backward stroke length of the bolt frame. When the bolt is located behind the hammer, the hammer cannot rotate in the firing direction due to restriction of the bolt frame, and the bolt does not be released when the bolt is behind the hammer, so that the reliability of automatic weapons is improved.

Description

technical field [0001] The present invention relates to light automatic weapons, in particular to automatic rifles, light machine guns and automatic shotguns. Background technique [0002] As known, when common automatic weapons are fired, the recoil spring cannot fully absorb the recoil energy of the bolt assembly (comprising the bolt and the bolt frame). The remaining energy will cause the bolt assembly to hit the receiver during the recoil stroke to generate recoil. This recoil force is an instantaneous impact force, which forms continuous interference and affects the accuracy of continuous shooting during continuous shooting. [0003] It is well known that the Ultimax100 light machine gun has a very low recoil force. The weapon offsets the recoil force generated when the bolt assembly hits the receiver by lengthening the recoil stroke of the bolt assembly. This principle is usually called the constant recoil principle (constant recoil). This type of weapon is usually K...
