Abstract: An automatic circulation shooting mechanism includes a gun body assembly, a gun barrel assembly, a bolt assembly, a recoil spring assembly, a triggering assembly, and a cartridge feeding assembly. Regarding the gun body assembly, a barrel fixing cap can separate from a barrel frame, so the gun barrel assembly mounted in the barrel frame can be replaced. The gun barrel assembly includes two barrel spring fixing seats disposed on a barrel, a barrel spring therebetween and a barrel extension. The barrel extension and a breech bolt of the bolt assembly are engaged for locking while shooting to allow the barrel and the breech bolt to recoil together by a linear freedom motion and affect the barrel spring, a bolt spring of the bolt assembly, and the recoil spring assembly for absorbing, storing, and releasing energy, thereby buffering recoil force of the shooting efficiently and attaining an automatic circulation shooting effect.

Abstract: A gas projectile platform having a trigger that can rotate when pressure is applied to the trigger, a first spool biased against a magnet, a pad assembly that, when actuated, allows pressure to enter an first spool pressure area forward the first spool and configured to release the first spool from the magnet when sufficient pressure is transferred to the first spool pressure area, the first spool configured to transmit pressure to a second spool wherein the second spool is configured to be positioned rearward overcoming a spring force to allow press to release from a bolt pressure area, wherein the bolt pressure area is pressurized when the bolt is in a forward position and configured to transition rearward when the second spool overcomes the spring force and wherein an ejection pressure stored in a bolt pressure area is transmitted to a chamber and ejects a projectile from a barrel.

Abstract: An action for a firearm uses a rotating barrel on which are mounted lugs and a cam follower. The barrel is positioned coaxially within a tube fixed to the frame of the firearm. A cam, engaged by the cam follower, is also fixed to the frame. A gas space is defined between the tube and the barrel by a thrust surface on the barrel and a reaction surface on the tube. A gas port connects the gas space with the barrel's bore. A slide overlies the tube and defines longitudinally oriented grooves which receive the lugs when the barrel is rotated by interaction between the cam and the cam follower to align the lugs and the grooves. Motion of the barrel is arrested by interaction between the cam and cam follower, and motion of the slide relative to the barrel is permitted when the lugs align and engage the grooves.

Abstract: A magazine safety is provided for a semi-automatic firearm having a frame with a magazine well, a magazine, and a firing mechanism that includes a trigger bar. The magazine safety includes a latch and a latch bias. When the magazine is not received within the magazine well, the latch bias biases the latch into engagement with the trigger bar, thereby preventing the actuation of the firing mechanism via the trigger bar. Inserting the magazine completely into the magazine well causes the magazine to disengage the latch from the trigger bar, thereby preventing the latch from impeding movement of the trigger bar.

Abstract: A semi-automatic handgun is disclosed including a frame having a barrel housing mounted thereon. A barrel is movably mounted on the barrel housing and has a cartridge chamber at its rearward end for receiving a cartridge therein. The barrel is movable between a rearward position and a forward position with respect to the barrel housing and is normally in its rearward position. The barrel moves forwardly in a straight line from its rearward position upon firing of the cartridge in the chamber to counteract the rearward energy of discharge, thereby reducing recoil. The handgun may be fired in either a single action or double action manner. The firing hammer of the handgun is re-cocked, upon firing of the cartridge, by means of a movable piston having a firing pin positioned therein with the firing pin engaging the hammer to move the hammer to its re-cocked position.

Abstract: A gun is provided with a loader and toggle link assembly for providing repeater action. The gun includes a frame, a barrel on the frame, and a forearm which is pivotally mounted on the frame. The loader is slidably mounted on the frame for movement between firing and loading positions. The toggle link is pivotally mounted on the frame and includes a first end portion which is connected to the loader and a second end portion which is engageable with the forearm. When the forearm closes, the toggle link pivots to move the loader to the firing position. When the forearm opens, a spring pivots the toggle link to move the loader to the loading position.

Abstract: A pump action firearm includes a barrel and a chassis defining a magazine well for receiving a magazine. The magazine well extends longitudinally parallel to the barrel and contains a plurality of cartridges arranged in stacked relationship with each cartridge having its longitudinal axis extending substantially transversely to a longitudinal axis of the barrel. A pump member displaces the barrel forwardly and rearwardly. A carrier mechanism is linked to the pump member and, during pumping of the pump member, moves an end cartridge contained in the magazine from its stacked position to an operative position in alignment with the longitudinal axis of the barrel.

A barrel has its rear end telescopically received within the sleeve, the barrel being axially movable from a rear firing position in close proximity to the breech to a forward loading position. The barrel is connected to the sleeve through a pin and groove arrangement so that axial movement of the barrel causes rotational movement of the sleeve. The sleeve being connected to the various mechanisms of the shot gun to operate these when it (the sleeve) is rotated.

Abstract: An apparatus for stunning animals and which has multiple propulsive charges. The apparatus is of the type in which a spike or plunger is projected toward the head of an animal to be slaughtered. The barrel of the apparatus is mounted on a part pivoted to the breech for pivotal movement about an axis parallel to the axis of the barrel. This arrangement mounts the barrel for pivotal movement between a position in which the barrel can be locked to the breech for firing, and a position in which the cartridge chamber of the barrel is aligned with cartridges in the cylinder of a magazine located in a handle connected to the breech. This arrangement permits simply pivoting the barrel into alignment with the magazine to load a cartridge into the chamber, and then pivoting the barrel back to the firing position in which it can be locked to the breech.

Abstract: An automatic weapon with a receiver, a breech block fixedly mounted in the receiver, a barrel reciprocable within the receiver, a spring biasing the barrel, and a gas cylinder chamber externally of the barrel and in communication therewith, whereby upon firing of the weapon, the gases discharged from a cartridge ejected from the barrel, pass into the gas cylinder chamber means to thereby tension the spring.

Abstract: A cartridge soft feed mechanism for presenting the cartridge to the chamber f a gun in such a way that the axis of the cartridge experiences no lateral or angular movement during chambering. The cartridge is telescoped into the chamber without ramping, reducing the probability of damage to the cartridge and reducing the chance of chambering stoppage. The feed mechanism is inactivated by a chambered round sensor for refilling the magazine or removing and replacing a chambered round in order to permit barrel movement between its forward extended position and its rearward ready position. While the current weapon (30mm Multishot Grenade Launcher) utilizes a fixed breech and movable barrel, the mechanism is adaptable to movable breech fixed barrel weapons.
