In this position, the topmost cartridge (2) is ready for feeding into a chamber (36) of the firearm (3) and in this position the topmost cartridge (2) rests against a pair of retaining lips (10). The lips (10) remain in a first position when the topmost cartridge (2) is in the upper position and the lips (10) are operatively displaceable to a second position wider than the first position.
A rifle with a replaceable barrel with two or more barrels for different purposes and calibers and with own magazines for different cartridges. At least one barrel (1) has the cavity (2), into which a projection or upper edge (4) in the cartridge magazine (3) corresponding to the barrel fits, when the right magazine has been inserted into the rifle.
A riflescope (11), which has an adjusting mechanism (16, 17) for aligning the rifle. By the adjusting mechanism (16, 17) there is provided a code, such as a pointer ring (12, 13, 14, 15) with a color code, according to the scale of which the adjusting mechanism for the riflescope (11) can be adjusted for correcting the ballistic trajectory of a bullet to be fired with the rifle.

A stock (10) for a firearm, provided with a stock frame section (3) and a releasably attachable cheekpiece (1, 2), in which the stock frame section (3) is symmetrical in relation to the longitudinal vertical direction of the stock, and when the cheekpiece (1, 2) is installed to the left side of the stock frame section (3), the stock becomes a right-handed stock, and when the cheekpiece (1, 2) is installed to the right side of the stock frame section (3), the stock becomes a left-handed stock. According to an advantageous embodiment the cheekpiece (1, 2) is adjustable, preferably quick- adjustable in height.
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.
The invention relates to a recoil pad of a firearm, consisting of a flexible and elastic damping cushion (2), which is attached to the butt of a firearm stock (1) and which rests against the shoulder (3) when shooting. Inside the recoil pad there is a displacement device (4), which in connection with compression creates an upward displacement in the recoil pad.
The invention relates to a lock of a magazine (1) for a firearm, consisting of a locking edge (2) in the magazine (1) and a magazine release (3), which rests on the locking edge and which is retained in the locking position by spring force (4). At the end of the magazine release (3) there is provided a backup cam (5), preventing the magazine release from opening before the magazine (1) is pushed inwards (A) so that the backup cam (5) can pass the locking edge (2) as the magazine release (3) is opened (B) for detaching the magazine.
A rifle with a replaceable barrel with two or more barrels for different purposes and calibres and with own cases for different cartridges. At least one barrel (1) has the cavity (2), into which a projection or upper edge (4) in the cartridge case (3) corresponding to the barrel fits, when the right case has been inserted into the rifle
A riflescope (11), which has an adjusting mechanism (16, 17) for aligning the rifle. By the adjusting mechanism (16, 17) there is provided a code, such as a pointer ring (12, 13, 14, 15) with a colour code, according to the scale of which the adjusting mechanism for the riflescope (11) can be adjusted for correcting the ballistic trajectory of a bullet to be fired wit the rifle.
