Abstract: A firearm attachable bullet trap (2) including a hollow body (3) configured to be releasable connected a muzzle end (7) of a rifle barrel (8) of a firearm (1). The hollow body (3) defining a ballistic plate chamber (9). The firearm attachable bullet trap (2) including a ballistic plate (12) in the ballistic plate chamber (9), and a bullet deforming part (14) within the hollow body (3), wherein the bullet deforming part (14) has a central channel (15), wherein the central channel (15) having a central axis A. The central channel (15) of the bullet deforming part (14) includes an open-sided channel section (17) that is radially limited by stationary cutter blades (18), wherein each stationary cutter blade (18) has a second proximal end (19) and a second distal (20). The stationary cutter blades (18) being equally spaced about the central axis A of the central channel (15).

Abstract: An assembly (1) for a firearm (2). The assembly includes a muzzle device (3) configured to be attached to the firearm (2), a substantially tubular muzzle adapter (9), a substantially tubular attachment mount (15), a substantially tubular clutch collar (19), and a device (23) such as a sound suppressor. The device (23) is releasably attached to the substantially tubular attachment mount (15) by an attachment device (25). The muzzle device (3) is configured to be releasably received in the substantially tubular muzzle adapter (9). 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) with respect to the device (23), to the muzzle device (3) and to the substantially tubular attachment mount (15) between (i) a locking position, and (ii) an unlocking position.
