A rifle has a receiver, a cartridge chamber connected to the receiver, and a bolt slideable longitudinally in the receiver, the bolt is engageable with a cartridge in the chamber. A bolt carrier is slideable longitudinally in the receiver to move the bolt into and out of engagement with a cartridge in the cartridge chamber, and a bolt handle is connected to the bolt carrier. The bolt handle is positionable in a manual position extending from one side of the rifle to permit manual firing of the rifle and in a semiautomatic position about 180 degrees different from the manual position and extending from the other side of the rifle to permit semiautomatic firing of the rifle. The position of the bolt carrier may be changed between the manual and semiautomatic positions without removing the bolt carrier from the rifle.

The invention relates to a firearm comprising: a housing (1) having a receptacle (2) for several cartridges or for a magazine with cartridges; a barrel unit (3) which is located in the housing (1) and has a barrel (4) and a cartridge chamber (6); a breechblock (8), which can be moved relative to the housing (1) and is biased in the firing direction by means of a return spring (7), for conveying cartridges into the cartridge chamber (6) or cartridge cases to an ejection port; and a gas braking device which is located in the housing (1) and comprises a cylinder (9) which is positioned parallel to the barrel (4) and which is connected to the interior of the barrel (4) via a gas extraction opening (10); and a piston (11) which can be moved inside the cylinder (9) and which is coupled to the breechblock (8). The breechblock (8) is located in a breechblock carrier unit (12) which is located completely inside the housing (1) over the entire movement path while a shot is being fired and during a reloading operation, the breechblock carrier unit (12) comprising the breechblock (8) itself, two connecting sections (13) guided parallel to the barrel (8) in the housing (1), and a coupling section (14) to be coupled with the piston (11) of the gas braking device.
