Abstract
A gun includes a bolt member that is disposed in a gun body so as to be movable forward and rearward, that moves rearward in response to gas pressure generated by bullet shooting so as to compress a bolt spring, and that moves forward in response to release of the compressed pressure so as to perform a bullet loading operation, and a bolt stop that stops forward movement of the bolt member. The bolt stop (31) has engagement means (36) for engaging with the bolt member which moves forward to reach the engagement means (36) after last bullet shooting, and includes buffer means (40) for buffering an impact force applied to the bolt stop due to the engagement so as to act on the bolt stop.
Claims6
A bolt stop buffer device in a gun comprising:
- a bolt member that is disposed in a gun body and moves forward and rearward, wherein the bolt member moves rearward in response to a gas pressure generated by a bullet shooting so as to compress a bolt spring, and the bolt member moves forward in response to release of the compressed pressure so as to perform a bullet loading operation;
- and
- a bolt stop that stops forward movement of the bolt member,
- wherein the bolt stop buffer device in a gun comprises an engagement portion and an engagement pair portion for engaging with the bolt member which moves forward to reach the engagement portion and the engagement pair portion after a last bullet shooting, and
- wherein the bolt stop buffer device in a gun further comprises a buffer mechanism, and the buffer mechanism buffers an impact force applied to the bolt stop due to the engagement so as to act on the bolt stop,
- wherein a bullet absence detector is disposed in the gun body and detects an absence of a bullet to be supplied to a bullet loading chamber,
- wherein the bolt stop moves upward in response to a detection of the absence of the bullet to be supplied to the bullet loading chamber, which causes an engagement between the engagement portion and the engagement pair portion, wherein the buffer mechanism buffers an impact force applied when the bolt member moves forward.
