An apparatus and method for providing power to an accessory on a firearm, the method including the steps of: detecting an accessory when attached to said firearm through actuation of a magnetic switch magnetically coupled to a magnet in the accessory via a pin located in the firearm and providing a power path with said accessory; and providing power to said accessory from a secondary source of power should power be required.

A sear mechanism for a firearm includes a trigger element having one or more contact surfaces on which one or more movable or pivotable components of the sear mechanism selectively contacts or slides. In some embodiments, the trigger element is made by producing an intermediate workpiece of the trigger element by a manufacturing process, and electric discharge machining the intermediate workpiece of the trigger element to provide the contact surfaces.

A firing mechanism for a firearm is provided for reducing maximum trigger pull weight attributable to a sear and for reducing trigger pre-travel and over-travel distances. By this, the likelihood of sear flutter phenomena is greatly reduced while also decreasing or maintaining maximum trigger pull weight. Also, hand movement during firing is reduced helping to increase accuracy.

An example firearm with a short overall length and improved storage compactness comprises a forward takedown subassembly comprising a barrel, a trigger control mechanism configured to provide an electrical trigger control signal, and a signal transmitter electrically coupled to the trigger control mechanism, and further comprises a rearward takedown subassembly separable from the forward takedown subassembly and comprising a stock, a receiver comprising an electrically controlled firing mechanism, and a signal receiver electrically coupled to the firing mechanism. A takedown mechanism has first and second portions fixedly coupled to the forward takedown subassembly and the rearward takedown subassembly, respectively, and is configured to repeatably couple the forward takedown subassembly to the rearward takedown subassembly. The signal transmitter and the signal receiver are configured to link the electrical trigger control signal to the signal receiver output via one or more of an electrical connection, an optical connection, and a radio-frequency link.

The invention relates to a trigger device for a semi-automatic handgun, including a locking element swivel-mounted around a first axis and acting on a trigger element via a locking face, and a shot limitation device, which has a control element with locking or control faces defining at least two locking positions for a pawl swivel-mounted around a second axis. To allow limited and precisely metered firing for rapid-fire sequences, it is provided that the control element is formed by a sear arranged in the path of action between a trigger and the trigger element, which acts on the trigger element through the locking element and the pawl swivel-mounted on the locking element around the second axis.

An ambidextrous bolt release that includes an ambidextrous bolt release lever; a bolt catch pivotable about a bolt catch pivot aperture between a bolt engagement and a bolt release position, wherein the bolt catch comprises a bolt engagement projection, and wherein the bolt catch comprises a bolt catch projection; and a connector bar extending from a first into a second end and attached or coupled between the ambidextrous bolt release lever and the bolt catch, such that vertical movement of the ambidextrous bolt release lever results in vertical movement of the connector bar and rotation of the bolt catch.

A trigger mechanism for a firearm is presented. The trigger mechanism has a trigger housing, a sear, a sear block and a trigger lever. Actuation of the trigger causes the trigger lever to rotate and eventually come into contact and move the sear block, which permits the sear to fall and permit the actuation of the firing mechanism.

A firing mechanism for a firearm is provided for reducing maximum trigger pull weight attributable to a sear and for reducing trigger pre-travel and over-travel distances. By this, the likelihood of sear flutter phenomena is greatly reduced while also decreasing or maintaining maximum trigger pull weight. Also, hand movement during firing is reduced helping to increase accuracy.

The invention relates to a method for acquiring the coordinates of a trigger point (P) of a projectile (4) above a field part (1) on which a target (5a, 5b, 5c) is located. The method is characterized in that it comprises the following steps: emission of at least one laser pulse having a pre-determined duration and directed towards the target (5a, 5b, 5c); reception of the images reflected with a receiver equipped with means for the synchronous visualization of the laser pulses originating from a piece of observation of the field part (1); recovery of the coordinates of a desired trigger point (P) when the operator has chosen a location after the piece of observation was moved. The invention also relates to a fire-control system using such a method.

A bump stock and interface system for a semi-automatic firearm. In use, the user grasps a handle with one hand and places an index finger of the same hand firmly on a finger rest. When intending to fire a round of ammunition, the user pushes the firearm receiver forward with another hand so that the trigger collides with the immobilized finger on the finger rest. Recoil force separates the trigger from the user's finger on the finger rest. The user again pushes forward the receiver to repeat the firing cycle. A lock is selectively activated to arrest longitudinal movement of the firearm relative to the handle, thereby returning the firearm to normal semi-automatic functionality. The lock includes a retractable pin having a tip that rides in a track having a rear stop to limit over-travel of the handle.
