A method, system, and apparatus for humanely dispatching wounded game in the field comprises a shank with a connecting end, a curved region, and a pointed end connected to a grip formed at the connecting end of the shank, and a finger loop. The grip can further comprise a series or flattened portions configured to engage the gaps in a choke tube in order to remove the choke tube.

A system includes a variable choke coupled to a barrel of a shot gun, and a mechanical mechanism coupled to the variable choke and configured to adjust an amount of choke constriction of the variable choke. The system further includes a motor coupled to the mechanical mechanism, and a control system configured to determine a desired size of a shot cone of shot fired from the shot gun, determine a choke constriction position of the variable choke that produces the identified size of the shot cone, and apply control signals to the motor to cause, via movement of the mechanical mechanism, automatic adjustment of the variable choke based on the determined choke constriction position of the variable choke.

A choke assembly for use with a shotgun, the choke assembly having a collar attachable to the muzzle of the shotgun. There is a sleeve attached to the collar, the sleeve having at least one tapered bore or aperture, a ball being received in the aperture. There is a tubular slide in surrounding relationship to the sleeve and the collar, there being annular radially outwardly and radially inwardly facing recesses on the slide and collar, respectively, which cooperate to form an annular spring pocket. There is a compression spring received in the pocket, the ball having a portion extending through the tapered bore and a threadless choke received in the sleeve, the choke having an indentation in which at least a portion of the ball is received when the choke is inserted into the sleeve.

A device enabling a shotgun operator to carry an additional choke tube on the body of a shotgun is disclosed. Embodiments include a universal adapter end cap configured to be threaded onto the end of a shotgun magazine, the universal adapter end cap including an opposite end adapted to secure an accessory (e.g., shotgun choke tube). Accordingly, embodiments enables an operator to stow and carry a second unused choke tube at the end of the shotgun magazine. Some embodiments of the universal adapter end cap include a threaded opening that enables the choke tube to be threaded into the threaded opening. Some embodiments provide threads constructed from flexible material to enable both threading and push insertion of an accessory into the universal adapter end cap.

A muzzle adaptation system facilitates the attachment of adaptors to the muzzle of a firearm. A converter is attached to the muzzle of a firearm using existing features such as threads. The adaptors are secured to the converter by a release device that allows the adaptor to be attached without precise alignment or fasteners.

An extension device (1) of a firearm (500) mounts in an operating configuration, to a muzzle (555) of a barrel (550) of the firearm (500). The extension device (1) includes a main body (10) which has an inner element (11) housable inside the barrel (550) and suitable to firmly engage with an inner barrel wall (550) and an outer element (12) which extends axially adjacent to the inner element (11) and is suitable to be arranged outside the barrel (550) with the inner element (11) housed in the barrel (550). The extension device further includes a secondary body (20) fitted axially on the main body (10) and an attachment body (30) fitted axially on the outer element (12) and fixable thereto performing an axial thrust action on the secondary body (20) until the secondary body presses against the muzzle (555) of the firearm (500).
