Abstract

A magazine catch body comprising a magazine and a magazine catch body comprising magazine catch buttons extended left and right, a magazine catch shaft connecting the magazine catch buttons to each other, and a magazine catch lever connected to the shaft for transmitting locking-releasing movements of the magazine catch buttons to the magazine to lock and release the magazine to the firearm, is disclosed. The magazine catch body comprises a spring around the shaft. The magazine catch buttons are substantially symmetrically located in respect of the firearm. The magazine catch buttons form the magazine catch body to one structural unity functionable as one mechanism. The magazine catch button extended left comprises a necked part pressing the lower receiver and receiving draw of the spring causing a holding force. In the necked part is an opening for a pin forming a turning axis of the magazine catch button extended left.

Abstract

The invention relates to a firearm (100) comprising a barrel (101) comprising a gas opening, and a gas system (10), which gas system (10) comprises a gas block (11), a gas piston (12), a force transmitter assembly (13), an indexing part (21) and an indexing counterpart (22), gas openings (18). The gas block (11) is fixedly attached to the barrel and the gas piston (12) is positioned by the indexing part (21; 22). In the gas system (10) gas is configured to pass through the gas opening of the barrel (101) via the gas openings (18) of the gas system into the gas block (11) and to set the gas piston (12) to movement. In the gas system (10) the gas piston (12) during its movement backwards is configured to close the gas opening of the barrel (101) for a defined time period and the gas piston (12) is not transmitting power/energy from combustion gas to the force transmitter assembly (13) unless the gas opening/-s (18) is/are closed.

Abstract

The invention relates to an aiming method, aiming system and computer program product utilized in the aiming method where also a real-time bullet velocity of a fired shot by a sniper rifle is utilized. The bullet velocity is measured in a suppressor in real-time for each fired shot. The suppressor sends the measured bullet velocity to a data logger of the sniper rifle. The data logger updates a bullet trajectory to a target after each fired shot and on the bases of an updated bullet trajectory the data logger sends new reticle setting to an optical scope connected to the sniper rifle.

Abstract

The invention relates to an aiming method, aiming system (10) and computer program product utilized in the aiming method where also a real-time bullet velocity (31) of a fired shot by a sniper rifle is utilized. The bullet velocity is measured in a suppressor (3) in real-time for each fired shot. The suppressor (3) sends the measured bullet velocity to a data logger (6) of the sniper rifle (1). The data logger (6) updates a bullet trajectory to a target after each fired shot and on the bases of an updated bullet trajectory the data logger (6) sends new reticle setting to an optical scope (2) connected to the sniper rifle (1).

Abstract

A method and a user interface are described for sighting in a virtual scope (100) of a virtual rifle. The point of the impact (118) of the virtual shot is determined, wherein the point of the impact (118) is based on ballistics (111) of the shot, a calibre (103) of the virtual rifle shooting the virtual shot and on a shooting distance (101) of the virtual shot. The virtual scope (100) is sighted in so that the virtual scope (100) can be sighted in based on the point of the impact (118) of the virtual shot. The virtual scope (100) have a substantial analogy with a real riflescope, thereby making the sighting in of the real scope more convenient.
