1. A barrel assembly comprising:

a monolithic upper receiver;

a first picatinny rail on an upper side of the monolithic upper receiver extending in a longitudinal direction, the monolithic upper receiver including an external angled contour that is complimentary to a downward recessed external contour of a handguard;

a barrel receptacle configured as an internal component of the monolithic upper receiver to receive a barrel and a locking socket, wherein the first picatinny rail extends beyond the barrel receptacle in the longitudinal direction; and

the locking socket including a first end and a second end, the first end positioned within the barrel receptacle and coupled to a barrel nut, the second end extending in the longitudinal direction opposite the first end, the second end including a circumferential stop that is positioned outside of the barrel receptacle.

2. The barrel assembly according to claim 1 , wherein the monolithic upper receiver is produced by one of extrusion or extrusion molding.

3. The barrel assembly according to claim 1 , wherein the monolithic upper receiver is produced from one of aluminum or an aluminum alloy.

4. The barrel assembly according to claim 1 , wherein the barrel receptacle extends in the longitudinal direction, and wherein an interior of the monolithic upper receiver includes a cylindrical inside section extending coaxially in the longitudinal direction to receive and store the barrel.

5. The barrel assembly according to claim 1 , wherein an internal profile of the monolithic upper receiver includes at least one guide rail, and wherein the at least one guide rail is integral in the monolithic upper receiver.

6. The barrel assembly according to claim 1 , wherein the barrel receptacle is configured integrally with at least one of a side wall, a lower side, or an upper side of the monolithic upper receiver.

7. The barrel assembly according to claim 1 , wherein a lower side of the monolithic upper receiver includes at least one connecting element to support the barrel receptacle.

8. The barrel assembly according to claim 7 , wherein the at least one connecting element includes at least one bar extending in the longitudinal direction, and wherein two bars form a cavity.

9. The barrel assembly according to claim 1 , wherein the barrel receptacle includes at least one recess to position the barrel.

10. The barrel assembly according to claim 1 , wherein at least one interface is formed integrally on the monolithic upper receiver or inside the monolithic upper receiver, and wherein the at least one interface is coupled to at least one of a handguard, a grip, a shoulder rest, or an additional attachment device.

11. The barrel assembly according to claim 1 , wherein a positioning element is coupled to one of the barrel or the locking socket mounted on the barrel, and wherein the positioning element is complementary to a recess in the barrel receptacle.

12. The barrel assembly according to claim 11 , wherein the barrel extends coaxially in the longitudinal direction and is coupled to the barrel receptacle of the firearm housing.

13. The barrel assembly according to claim 12 , wherein a stop element is provided at one of the barrel or the locking socket to position and fix the barrel in the barrel receptacle.

14. A method for producing a barrel assembly, comprising:

producing a monolithic upper receiver, a first picatinny rail on an upper side of the monolithic upper receiver extending in a longitudinal direction, the monolithic upper receiver including an external angled contour that is complimentary to a downward recessed external contour of a handguard; and

configuring a barrel receptacle as an internal component of the monolithic upper receiver to receive a barrel and a locking socket, wherein the first picatinny rail extends beyond the barrel receptacle in the longitudinal direction, the locking socket including a first end and a second end, the first end positioned within the barrel receptacle and coupled to a barrel nut, the second end extending in the longitudinal direction opposite the first end, the second end including a circumferential stop that is positioned outside of the barrel receptacle.

15. The method according to claim 14 , wherein the monolithic upper receiver is produced by one of extrusion or extrusion molding.

16. The method according to claim 14 , wherein an interior surface of the monolithic upper receiver includes at least two guide rails extending at least partially a length of the monolithic upper receiver.
