摘要： A semi-automatic or fully automatic firearm (2) having a barrel (4), the rear end of which is in the form of a cartridge chamber (8), in which each round can be inserted from the rear; a breech body (6) that is movable in a longitudinal direction of the barrel between an open position for releasing the cartridge chamber (8) for reloading a round and a locking position that locks the cartridge chamber (8), wherein in the locking position the breech body (6) closes the cartridge chamber (8) at the rear and the cartridge casing acts as a thrust bearing, wherein the firearm (2) has a breech body locking device (20) that is designed to move a breech body lock from a breech body release position for releasing the breech body (6) to a breech body locking position for locking the breech body (6) and from the breech body locking position to the breech body release position, wherein the breech body locking device (20) has an electromagnet (24) for moving the breech body lock from the breech body release position to the breech body locking position, and/or an electromagnet (24) for moving the breech body lock from the breech body locking position to the breech body release position, as well as a firearm (2) with an electromagnetically driven firing pin (18).

摘要： 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.

摘要： An integrated magazine and bolt release mechanism that is intended to automate the operations of magazine release when empty, and bolt release when a loaded magazine is inserted into the rifle. The release mechanism may include a mechanical switch device. The mechanical switch device may be a lever that is able to identify the presence of ammunition. By way of mechanical linkage, the system is able to control the magazine catch surface to either maintain or expel a magazine. The linkage facilitate the transition of vertical motion, imparted by the magazine body and follower to the lever into horizontal motion of an arm to move the magazine catch in and out of engagement with the magazine's locking surface. Upward vertical motion of the lever may actuate the bolt catch surface by means of a mechanical link that serves to reverse the direction of vertical motion. As the magazine body moves upward, the lever impinges on the arm that forces the bolt catch downward, to release the locked bolt group.
