DETAILED DESCRIPTION

An assembly 1 for a firearm 2 and some embodiments and variants of the assembly are described below. 1 will be described in greater detail.

The assembly 1 has preferably, but not necessarily, a longitudinal central axis A.

The assembly 1 comprises a muzzle device 3 configured to be attached to a muzzle of a barrel 4 of the firearm 2. The muzzle device 3 has a first proximal end 5, and a first distal end 6. The muzzle device 3 is provided with a number of successive locking teeth 7 and first channels 8 around an outer circumference (not marked with a reference numeral) of the muzzle device 3.

The assembly 1 comprises a substantially tubular muzzle adapter 9 having a first tubular body 10, a second proximal end 11, and a second distal end 12. The substantially tubular muzzle adapter 9 is provided with a number of successive locking lugs 13 and second channels 14 around an inner circumference (not marked with a reference numeral) of the substantially tubular muzzle adapter 9.

The assembly 1 comprises a substantially tubular attachment mount 15 having a second tubular body 16, a third proximal end 17, and a third distal end 18.

The assembly 1 comprises a substantially tubular clutch collar 19 having a third tubular body 20, a fourth proximal end 21, and a fourth distal end 22.

The assembly 1 comprises a device 23 such as a sound suppressor, a blank firing bullet trap, or a reinforcement bar cutter having a fifth proximal end 24.

In the assembly 1, the device 23 is releasably attached to the substantially tubular attachment mount 15 by means of attachment means 25.

Because the device 23 is releasably attached to the substantially tubular attachment mount 15, the device 23 can be changed or replaced with another device 23.

In the assembly 1, the muzzle device 3 is configured to be releasably received in the substantially tubular muzzle adapter 9 so that co-operating rotation prevention means 26 of the muzzle device 3 and at least one of the device 23 and the substantially tubular attachment mount 15prevents the muzzle device 3 from rotating with respect to the device 23 and/or to the substantially tubular muzzle adapter 9 about the longitudinal central axis A.

In the assembly 1, the muzzle device 3 can, as in the embodiment of the assembly illustrated in FIGS. 19 to 23, be configured to be releasably received in the substantially tubular muzzle adapter 9 so that the first distal end 6 of the muzzle device 3 extends into the fifth proximal end 24 of the device 23. In such case, the co-operating rotation prevention means 26 are preferably, but not necessarily, formed at least partly of tines 49 of the muzzle device 3 and by recesses 50 in the device 23 sized and shaped for complementary receipt of at least a portion of the tines 49 of the muzzle device 3, as in the embodiment of the assembly illustrated in FIGS. 19 to 23.

In the assembly 1, the substantially tubular muzzle adapter 9 is attached to the substantially tubular clutch collar 19 for rotation about the longitudinal central axis A together with the substantially tubular clutch collar 19 and by means of the tubular clutch collar 19 with respect to the device 23, to the muzzle device 3 and to the substantially tubular attachment mount 15 between (i) a locking position, where successive locking teeth 7 of the muzzle device 3 are in the direction of the longitudinal central axis A at least partly aligned with the locking lugs 13 of the substantially tubular muzzle adapter 9 so as to prevent relative movement between the muzzle device 3 and the substantially tubular muzzle adapter 9 in the direction of the longitudinal central axis A, and (ii) an unlocking position, where successive locking teeth 7 of the muzzle device 3 are in the direction of the longitudinal central axis A aligned with the second channels 14 of the substantially tubular muzzle adapter 9 and where successive locking lugs 13 of the substantially tubular muzzle adapter 9 are in the direction of the longitudinal central axis A aligned with the first channels 8 of the muzzle device 3 so as to allow relative movement between the muzzle device 3 and the substantially tubular muzzle adapter 9 in the direction of the longitudinal central axis A.

The assembly can for example be configured to be used and be configured to function as presented in the following: The muzzle device 3 is fastened to the barrel 4 of the firearm 2. The substantially tubular muzzle adapter 9, the substantially tubular attachment mount 15, and the substantially tubular clutch collar 19 as well as other parts of the assembly are assembled together, if not already assembled together. The device 23 is attached to the substantially tubular attachment mount 15. The muzzle device 3 is brought into the substantially tubular muzzle adapter 9 of the assembly 1 from the second proximal end 11 of the substantially tubular muzzle adapter 9. The substantially tubular muzzle adapter 9 is rotated about the longitudinal central axis A with the substantially tubular clutch collar 19 into the unlocking position, where successive locking teeth 7 of the muzzle device 3 are in the direction of the longitudinal central axis A aligned with the second channels 14 of the substantially tubular muzzle adapter 9 and where successive locking lugs 13 of the substantially tubular muzzle adapter 9 are in the direction of the longitudinal central axis A aligned with the first channels 8 of the muzzle device 3 so as to allow relative movement between the muzzle device 3 and the substantially tubular muzzle adapter 9 in the direction of the longitudinal central axis A, whereafter the muzzle device 3 is brought through the muzzle adapter 9 so that the so that the first distal end 6 of the muzzle device 3 extends into the fifth proximal end 24 of the device 23 and so that co-operating rotation prevention means 26 of the muzzle device 3 and at least one of the device 23 and the substantially tubular muzzle adapter 9 prevents the muzzle device 3 from rotating with respect to the device 23 and/or to the substantially tubular muzzle adapter 9 about the longitudinal central axis A. Thereafter the substantially tubular muzzle adapter 9 is manually or automatically rotated about the longitudinal central axis A with the substantially tubular clutch collar 19 from the unlocking position into the locking position, where successive locking teeth 7 of the muzzle device 3 are in the direction of the longitudinal central axis A at least partly aligned with the locking lugs 13 of the substantially tubular muzzle adapter 9 so as to prevent relative movement between the muzzle device 3 and the substantially tubular muzzle adapter 9 in the direction of the longitudinal central axis A.
