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.

Claim (Index 2):
The bolt stop buffer device in a gun according to  claim 1 ,\n wherein the gun body has a bullet absence detection means for detecting the presence or absence of a bullet to be supplied to a bullet loading unit in response to a gun operation, and wherein the bullet absence detection means detects a bullet absence, and includes a link mechanism for communication which enables the engagement means to engage with the bolt member by causing the bolt stop to protrude into a track when the bolt member moves forward and rearward.
