Abstract: A firearm choke tube includes a cylindrical body, a choke interrupted thread section, and a locking tab. The choke interrupted thread section is positioned on an outer surface of the cylindrical body and configured to threadably engage an interrupted thread section of a barrel of a firearm to limit longitudinal movement of the cylindrical body relative to the barrel. The locking tab protrudes from the outer surface of the cylindrical body and is configured to interface with a detent formed in the barrel to limit rotational movement of the cylindrical body relative to the barrel.

Abstract: Improved gun with automatic loading of cartridges, comprising a cartridge loader in the form of a tubular magazine (4), characterized in that: The magazine bottom (18) is mounted in a way so that it can slide in the axial direction (X-X?) with respect to the tubular magazine (4). The sliding magazine bottom (18) is equipped with a shock absorber (26) able to absorb the shocks exerted on the magazine bottom (18) in the axial direction (X-X?) of the tubular magazine (4). The cartridge follower assembly (19) provided with a shock absorber (29) that can absorb the shocks exerted on the follower assembly (19) in the axial direction (19) of the tubular magazine (4).

Abstract: A magazine for a firearm may include a cavity that is shaped to prevent the tip of the bullets in the cartridges from contacting the magazine when the firearm recoils. The magazine may also be configured so that the cartridges in the magazine exit the cavity at least approximately in the center of the magazine. The magazine may be configured to include a biasing mechanism that pushes the cartridges upward in the cavity. The biasing mechanism may be configured to allow the magazine to be compact, simple, and reliable.

Abstract: A water bottle includes a bottle body, a cap and a base. The bottle body includes a wall structure extending from a bottom end to a top end. The top end includes an opening. An outer surface of the wall structure may include a plurality of finger grip recesses and at least one thumb grip recess. The cap is configured to releasably connect to the top end of the bottle body to close the opening with a fluid-tight seal. The cap has a pointed portion that provides at least one top pressure point. The base is positioned at the bottom end of the bottle body and includes at least one pointed portion that provides at least one bottom pressure point. The at least one top and at least one bottom pressure points provide self-defense features for the water bottle.

Abstract: Firearm comprising a receiver (2); a barrel (6) mounted with one end on the receiver (2); a breech (8) equipped with a loading lever (9) mounted, in a way so that it can slide, in the receiver (2); at least one return spring (15) to return the breech (8) to its closed position, characterised in that the return spring (15) is a tension spring of the ‘constant-force’ type that is mounted between the breech (8) and a fixed support (12) with respect to the receiver and the barrel.

Abstract: Butt with recoil pad for a shoulder-held firearm, with the butt comprising a recoil pad, characterized in that the recoil pad is mounted on the butt by means enabling the position of the recoil pad to be adjusted with respect to the butt so as to be able to personalize the position of the recoil pad for the shooter with respect to an average position in which the recoil pad is primarily located in the extension of the butt.

Abstract: A folding knife includes a handle, a knife blade rotatably attached to the handle, the knife blade including a tang, a liner positioned within the handle, the liner further comprising a liner lock, and a safety device. The liner lock has a first position when the knife is in a closed position, and has a second position when the knife blade is in a deployed or open position. An end of the liner lock engages the tang of the knife. A safety device is positioned between the liner lock and the handle when the knife blade is in the deployed or open position.

Abstract: Shoulder fire arm comprising a frame a barrel and a stock for holding the weapon against the shoulder and or the cheek of the gunman wherein the stock is formed of a body and a recoil pad at the end of this body, the recoil pad being connected to the body of the stock by means of a shock absorber and the absorber is placed in such a way that during the shot the stock moves down from the shoulder and cheek of the gunman.

Abstract: A shotgun includes an action that is capable of rapidly chambering a shotshell after the shotgun has run out of shotshells and is capable of allowing shotshells to be removed from the magazine without cycling the shotshells through the action.
