A trigger reset that is disposed in a firearm handle including an electric motor, a battery, a gear box and cam lobe mounted on a shaft of the motor. A reset bar assembly is secured to the cam lobe. As shaft turns, cam lobe moves to provide a reciprocating motion to reset bar assembly. The reset bar assembly may be biased in lateral directions via a spring or the like. Rearward movement of the firearm trigger causes movement of the reset bar assembly in a rearward longitudinal direction. When the trigger reset is actuated, the motor rotates the cam lobe moving the reset bar assembly in a forward position thereby urging the trigger to a reset position prior to actuating the next firing sequence. The reset trigger system further includes a switch defining a face portion that is positioned on the exterior surface of the grip and immediately below the trigger for easy accessibility when holding or firing the firearm.

A trigger device for activating a firing mechanism, the trigger device comprising a housing, a trigger pivotally mounted on the housing via a trigger pivot pin, a sear arm comprising a first sear surface, a ticker extending generally from the trigger to the sear arm, the ticker pivotable about a ticker pivot pin, the ticker comprising spaced apart flanges, each of which comprises an aperture defining at least a first contact surface, and a captured roller positioned at least partially within the apertures, wherein in a captured position the first sear surface and the first contact surfaces engage the captured roller and in a released position the first contact surfaces disengage from the captured roller to allow the captured roller to move within the aperture.

Trigger groups for semi-automatic firearms have a frame, a hammer connected to the frame and movable between a cocked position and a striking position, the hammer being biased toward the striking position, a trigger element connected to the frame and movable by a user between a forward position and a rearward position, a selector connected to the frame and movable between at least a first position and a second position, and a plurality of retention facilities each operable to selectively restrain the hammer in the cocked position, and when the selector is in the second position to enable discharge of the firearm in response to movement of the trigger to the forward position after movement to the rearward position and to enable an additional discharge of the firearm upon release of the trigger to the forward position.

Semi-automatic rifle including a free floating barrel with a muzzle located at a distal end and an engagement mechanism at a proximal end. The barrel has a length measured from the proximal end to the distal end. A receiver can be configured to couple the engagement mechanism of the barrel and a bolt at least partially rotatably mounted relative to the receiver. A gas cylinder system being coupled to the barrel substantially close to the muzzle and including an operating rod. A trigger assembly coupled to the receiver to receive at least a portion of the operating rod and a bridge coupled to the trigger assembly. A fire control located substantially within the trigger assembly and configured to actuate the bolt so as to eject a cartridge and load a subsequent cartridge from a clip.

This invention is characterized by its appearance as a bracelet or a wrist watch, for example. The distinctive features of this device are its micro size, stealth-ness, and light weight. The object of this invention is to a provide state-of-the-art personal protection in two forms, a firearm and a knife, both of which are totally concealable even if the wearer is not wearing clothes. They are both instantly available and easily deployed to protect oneself from an imminent threat.

Trigger groups for semi-automatic firearms have a hammer, a trigger element, a sear, a selector, and a disconnector assembly, the disconnector assembly operable when the selector is in a first position to retain the hammer in the cocked position in response to release of the trigger element to the rest position subsequent to discharge of the firearm by pulling the trigger element, and the disconnector assembly operable when the selector is in a second position to release the hammer to the striking position in response to release of the trigger element to the rest position subsequent to discharge of the firearm by pulling the trigger element, such that the firearm discharges once per cycle of the trigger element when the selector is in the first position, and fires once for each forward or rearward motion of the trigger element when the selector is in the second position.
