A shoulder arm, especially a rifle, having a barrel, a recess, which is perpendicular to the axis of the barrel, formed in a member which is fixedly connected with the barrel, and a roller-shaped breech member coaxially arranged in the recess and capable of being swivelled about its longitudinal axis for loading. The breech member contains a firing chamber which, in the firing position of the breech member, is in alignment with the barrel and is closed to the rear. The shoulder arm also has an arrangement for swivelling the breech member out of the firing position and into a loading position, in which the firing chamber is accessible for the introduction of a cartridge. The recess is designed in the form of a cylindrical hole, whose wall serves to mount the roller-shaped breech member and to directly close the firing chamber when it is located in the firing position. The breech member is retained in its respective position by means of the swivelling arrangement which can only rotate the breech member in one direction. A magazine and an ejector, are mounted on the same side of the shoulder arm or weapon and above the barrel.

Shoulder arm with swivel breech member

The invention relates to a loading arrangement for handfire-arms, in particular automatic rifles for firing caseless ammunition, comprising a magazine and a cartridge clip adapted to it. The cartridge clip retains the cartridges by two resilient tongues and is constructed as an insert for a container. Several containers are detachable interconnected. The magazine comprises channels for the tongues and is provided with a one-way barrier at the front face, which is open over at least approximately the full cross-section. The one-way barrier allows the insertion of a cartridge clip having a plurality of cartridges into the magazine, tensioned against the follower spring. The one-way barrier further permits the removal of the clip while retaining the cartridges in the magazine. The cartridges are removed from the magazine perpendicular to the direction of insertion. The one-way barrier is constructed as a U-shaped stop spring.

Means for loading small firearms including a box magazine and cartridge

A weapon includes a receiver which defines a dust-tight and water-tight space accommodating a barrel and a bolt assembly slidably carried by the barrel at the breech thereof. An ignition device is arranged within the space defined by the receiver for igniting, at predetermined times, combustible gases accumulating in that space.
