Abstract: A rifle has a fixed main body, including a barrel, a receiver with an upper opening, and a breech element. A trigger group is at least partially housed in the receiver, including a trigger, a hammer device operable by the trigger, and a safety member positionable in a shooting position, disengaged from the hammer device and in a safety position, engaged with and blocking the hammer device. A carriage assembly with a shutter group is positioned on the receiver at the upper opening and axially movable by the user between an advanced shooting configuration and a retracted rearming configuration. The carriage assembly includes a safety group controllable by the user, with the carriage assembly in the advanced configuration, in a ready-to-shoot configuration, in which it is disengaged from the safety member, and a safety configuration, in which it engages and keeps the safety member in the safety position.

Abstract: A firearm system is provided. A pump-action firearm, such as a shotgun, includes a buffer attached to a trigger housing. The buffer consists of a resilient or semi-resilient material and is positioned such as to face towards an opening the receiver in which the magazine tube is partially received. The buffer includes a contoured bottom surface and an upper surface, configured in a way which shortens the space available within an opening of a receiver while accommodating the loading of shells into a magazine tube. Upon moving a shell into the opening, such as by pumping the action, the shell impacts the buffer, which stabilizes the shell prior to being lifted by an elevators. For shorter shells, this reduces the risk of a jamming event. For longer shells, the buffer is configured to compress to accommodate the additional length.

Abstract: A high capacity handgun/pistol is disclosed with a horizontally oriented magazine that is aligned with and disposed beneath the gun barrel. The magazine defines a plurality of hollow tubes arranged radially around a central axis about which the magazine can rotate automatically during operation of the handgun/pistol. The hollow tubes each contain a plurality of ammunition rounds, and can each be aligned with a loading tray one at a time, wherein a coil spring will push out a single round at a time onto the loading tray. The handgun uses a gun slide to load a new round into the chamber via the loading tray, and further enabling the loading tray to automatically rotate the magazine as each hollow tube becomes empty. Moreover, the slide will re-set a hammer to re-engage with a sear, after a pulled trigger releases the hammer to strike a firing pin.

Abstract: A collapsible pistol features enhanced safety, ease of use, and improved performance as compared to prior designs. The pistol is easily reconfigured from an open, ready-to-fire position to a closed or collapsed position that makes the pistol quite compact, safe, and readily concealable. The overall design of the pistol is such that the manipulation of the pistol into and out of the open, ready-to-fire position can be accomplished with a user having relatively small hands and/or relatively low grip strength.

Abstract: Disclosed is an anti-bounce firearm hammer including a hammer member mountable in a firearm for pivotal movement about an axis. The hammer member includes a head portion with a strike face radially spaced from the pivot axis. A mass is attached to and movable with the hammer member in a direction substantially toward and away from the strike face. The mass has freedom of movement such that the mass will continue to move a limited distance independent of the hammer member after pivotal movement of the hammer member has stopped.

Abstract: The present invention provides a means for restricting access to the trigger guard enclosure of a long gun. The present invention enshrouds the perimeter of the trigger guard enclosure preventing access when not in use. When the weapon is in use, the present invention slides away from the trigger guard enclosure and secures as a handgrip for use while aiming and firing the weapon, all the while remaining permanently affixed to the weapon.

Abstract: A magazine cutoff device for a firearm with a tube-type magazine, such as, e.g., semi-automatic shotgun. The cutoff device may be moveably mounted to accommodate at least two positions, on and off. The user may activate the cutoff, pull the bolt to the rear, eject a chambered shell, and lock the bolt to the rear while retaining any shells in the magazine.

Abstract: A trigger safety for a firearm having a frame and slide. The safety includes a safety assembly frame mountable within the firearm frame. The safety also includes at least one actuator operatively attached to the safety assembly frame, the actuator being capable of selectively moving the safety assembly frame between a first position and a second position. The assembly frame also has an abutment surface. In the first position the abutment surface contacts a trigger bar of the firearm preventing movement of the trigger and discharge of the firearm while allowing the slide to be cycled and in the second position the abutment surface is not in contact with the trigger bar and the firearm can be discharged.

Abstract: A pump gun is disclosed having a loading and firing mechanism which comprises a cartridge stop lever (21), that is not connected to the hammer, interacts with the cocking slide (22) associated with the cartridge magazine and is susceptible to rocking movements on an intermediate pin (30) between an operating interception position of a first cartridge in the magazine, when the cocking slide is in a retracted work position, and an idle release position of the same cartridge from the magazine tube, when the cocking slide is in the forward rest position.

Abstract: A carrier lock for use in semi-automatic firearms.

Abstract: In a firearm having a trigger assembly with a trigger nose, a hammer with a sear hook and a trigger notch, a disconnector and an automatic sear, an improvement including a notched bifurcating the sear hook of the hammer for receiving the disconnector in a past-cocked position. Further improvements include the trigger notch being offset rearwardly from a center of the pivot point resulting in a slightly changed angle away from an acute engagement angle with the trigger nose.

Abstract: A carrier lock for use in semi-automatic firearms.

Abstract: The present invention relates to an automatic bolt hold-open rotating assembly to convert a manual bolt hold-open function to an automatic bolt hold-open function in automatic and semi-automatic pistols and rifles, such as the Ruger 10/22 semi-automatic .22 caliber rifle. The components of the assembly readily replace standard factory components in the trigger assembly and replace the standard magazine. The assembly comprises a magazine with channel cutout, a bolt stop, a bolt stop handle for manual manipulation of the assembly, a bolt stop spring to apply clockwise pressure on assembly, a cartridge detecting lever which also serves as a cartridge ejector pivotably mounted on bolt stop with an extension which interfaces with channel cutout of magazine, a tab protruding from the ejector lever which rides in a slot on the bolt stop to limit pivoting of the cartridge detecting lever, and a lever spring allowing counter-clockwise pivoting of cartridge detecting lever to facilitate insertion of recharged magazine.

Abstract: A cartridge follower for pushing against cartridges in a tubular magazine of a shotgun. A front face of the follower has at least one forwardly protruding member offset from the center of the front face to be tactilely distinguished from a cartridge in the magazine, but which cannot contact a central primer of a backwards cartridge. A method for determining whether a shotgun is empty includes providing such a follower in the magazine, inserting a finger into the outfeed end of a magazine, and attempting to feel the protruding member.

Abstract: A repeating rifle having a chamber to which a magazine guide is secured by means of threaded bolts, into which magazine guide a bar magazine can be inserted, can selectively receive a longer magazine. In order to make this possible with a minimum of parts and manual operations, there is provided an adapter which fits onto the chamber or onto a stock and is secured by means of bolts which are screwed into threaded bores in that end of the threaded bolts which faces away from the chamber.

Abstract: A semi-automatic gas-operated shotgun includes a safety device which locks the firing mechanisms of the gun and simultaneously locks the breech-block slide in the open position, spaced from the cartridge chamber of the gun, by the operation of a single safety button.

Abstract: A compressed gas weapon (10) is configured in the breech portion (18) of its barrel (12) to accommodate a projectile (24) in a position of readiness to fire and to reproducibly caliber the projectile (24) in the process of conveying it into the position of readiness to fire.

Abstract: Disclosed is a device suitable for semi-automatic rifles, and capable of timely feeding cartridges into the firing chamber without causing void loading of the weapon.The improved device comprises a sliding member controlled by the hammer and cooperating with a trowel-like lift. The device operates so as to position the lift for receiving a fresh cartridge from the magazine in advance of the striking of the firing pin by the hammer.
