The invention relates to a firearm, in particular for shooting cartridge ammunition, having at least one weapon chassis 3, a weapon system support 4, and a weapon system apparatus 5; at least the weapon chassis 3 and the weapon system support 4 have corresponding engagement means 10 provided in spacing patterns via which they can be axially positioned differently relative to each other.

A modular barrel system for firearm includes a first barrel segment and a second barrel segment. Each barrel segment comprises a tubular member having an axial bore, a proximal end, and a distal end. The proximal end of the first barrel segment has a first threaded element for removably attaching the first barrel segment to a firearm. The distal end of the first barrel segment has a second threaded element and the proximal end of the second barrel segment has a third threaded element which is complementary with the second threaded element, the third threaded element for removably attaching the second barrel segment to the first barrel segment. In a further aspect, method for the manufacture of a modular barrel system are provided.

An assembly (10) includes a receiver body (12) that includes a butt (14), a body trigger (16), a grip (18), and a display screen (20). A variable-length shaft (24) extends from a front portion of the receiver body (12). A firearm receiver member (36) is coupled to a distal end of the variable-length shaft (24) by means of a coupling device (42), and a camera (40) is in communication with, and is configured to send images to, the display screen (20).
