The firearm has a barrel and a breech. The component carrier comprises a grip portion for receiving at least a portion of the barrel, a housing portion for receiving at least the breech, and a coupling member in a transition zone between said two portions for coupling the barrel with the breech. The grip portion is separated into a support part radially supporting the barrel, and a spacer part keeping the support part axially spaced from the coupling member. The spacer part is configured to receive the barrel with radial clearance. ## Claims ### Claim 1 A component carrier for a firearm, the firearm having a barrel and a breech block, comprising: a grip portion for receiving at least a portion of the barrel, a housing portion for receiving at least the breech block, and a coupling member in a transition zone between said the grip portion and housing portion for coupling the barrel with the breech block, wherein the grip portion is separated into at least two component parts comprising a support part radially supporting and axially guiding the barrel, and a spacer part keeping the support part axially spaced from the coupling member, which spacer part is configured to receive the barrel with radial clearance, and wherein the support part is mounted on the spacer part. ### Claim 2 (depends on 1) The component carrier of claim 1, wherein the support part extends from the spacer part in an axial direction. ### Claim 3 (depends on 2) The component carrier of claim 2, wherein the support part has a recessed portion inserted into the spacer part. ### Claim 4 (depends on 1) The component carrier of claim 1, wherein the support part is configured to be mounted on the barrel. ### Claim 5 (depends on 1) The component carrier of claim 1, wherein the support part is mounted on the spacer part. ### Claim 6 (depends on 1) The component carrier of claim 1, wherein the coupling member forms a bayonet coupling for an exchangeable barrel, and wherein the component carrier is provided with a releasable lock for the bayonet coupling. ### Claim 7 (depends on 6) The component carrier of claim 6, wherein the bayonet coupling comprises a bore in said transition zone with at least one inner toothed ring for engagement of a matching outer toothed ring of the barrel, and a stop for limiting a rotation of the barrel. ### Claim 8 (depends on 6) The component carrier of claim 6, wherein the lock of the bayonet coupling acts between the support part and a counter piece which can be mounted on the barrel. ### Claim 9 (depends on 7) The component carrier of claim 7, wherein the lock of the bayonet coupling acts between the support part and a counter piece which can be mounted on the barrel, and wherein the stop is formed on the support part and cooperates with a lug of the counter piece. ### Claim 10 (depends on 8) The component carrier of claim 8, wherein the support part comprises a movable locking bolt for selectively engaging a recess of the counter piece. ### Claim 11 (depends on 10) The component carrier of claim 10, wherein the locking bolt is spring loaded and received in a bushing of the support part, and wherein an operating element accessible from outside actuates said locking bolt, which operating element is guided in a slot of a wall of one or more of the bushing and the support part. ### Claim 12 (depends on 8) The component carrier of claim 8, wherein the counter piece comprises a cylinder-piston unit fed by a barrel tapping, and wherein the piston acts upon a rod assembly guided in the grip portion for rapid firing. ### Claim 13 (depends on 12) The component carrier of claim 12, wherein the barrel tapping is provided with a pressure control valve. ### Claim 14 (depends on 1) The component carrier of claim 1, wherein the coupling member is fitted exchangeably into the component carrier. ### Claim 15 (depends on 1) The component carrier of claim 1, wherein each of the spacer part and the support part carries on at least one side a mounting rail, said mounting rails being mutually aligned. ### Claim 16 (depends on 15) The component carrier of claim 15, wherein the mounting rail of the spacer part extends over the housing portion. ### Claim 17 (depends on 8) The component carrier of claim 8, wherein the counter piece carries on at least one side a further mounting rail. ### Claim 18 A firearm, comprising: a barrel, a breech block and a component carrier, wherein the component carrier comprises: a grip portion for receiving at least a portion of the barrel, a housing portion for receiving at least the breech block, and a coupling member in a transition zone between said two portions for coupling the barrel with the breech block; and wherein the grip portion is separated into at least two components comprising a support part radially supporting and axially guiding the barrel, and a spacer part keeping the support part axially spaced from the coupling member and receiving the barrel with radial clearance; the coupling member forms a bayonet coupling for an exchangeable barrel and the component carrier is provided with a releasable lock for the bayonet coupling; and further wherein the lock of the bayonet coupling acts between the support part and a counter piece mounted on the barrel. ### Claim 19 (depends on 1) The component carrier of claim 1, wherein the spacer part includes a larger diameter bore than the bore of the support part. ### Claim 20 A component carrier for a firearm, the firearm having a barrel and a breech block, comprising: a grip portion for receiving at least a portion of the barrel, a housing portion for receiving at least the breech block, and a coupling member in a transition zone between said the grip portion and housing portion for coupling the barrel with the breech block, wherein the grip portion is separated into a support part radially supporting the barrel, and a spacer part keeping the support part axially spaced from the coupling member, which spacer part is configured to receive the barrel with radial clearance, and wherein the support part is mounted on the spacer part, wherein the coupling member forms a bayonet coupling for an exchangeable barrel, and wherein the component carrier is provided with a releasable lock for the bayonet coupling, wherein the lock of the bayonet coupling acts between the support part and a counter piece which can be mounted on the barrel, wherein the support part comprises a movable locking bolt for selectively engaging a recess of the counter piece, the locking bolt is spring loaded and received in a bushing of the support part, and wherein an operating element accessible from outside actuates said locking bolt, which operating element is guided in a slot of a wall of one or more of the bushing and the support part.
