A bullpup stock assembly configured for housing a firearm assembly without the use of tools. The bullpup stock includes an upper housing configured to hingedly couple with a lower housing. A hinging means hingedly couples the upper and lower housings such that in a closed configuration the forward ends upper and lower housing are joined, and such that in an open configuration the upper and lower housing are not joined. A bullpup trigger is configured to communicate with a trigger of the firearm assembly by a trigger linkage assembly such that the bullpup trigger activates the firearm when depressed. A block assembly housed with the upper and lower housings is configured to house a firing assembly of the firearm and the trigger linkage assembly. At least one locking means for locking the upper and lower housings together when the forward ends of the upper and lower housing are joined.

A firearm system for monitoring the displacement of a firearm trigger during a trigger pull includes a firearm body including a handle and a barrel attached to the handle. A trigger is attached to the firearm body, and a position input circuit is attached to the trigger. The position input circuit emits a trigger position signal including information representative of the trigger displacement. The firearm body is in wired or wireless communication with an electronic device. The electronic device can include a monitor, or screen, for graphically displaying a trigger position indicator representative of the displacement of the trigger along one or more axes. The firearm body can include a motion sensing circuit generally adapted to detect motion of the firearm body. The motion sensing circuit can include one or more accelerometers or gyroscopes. A wireless transmitter or transceiver can be positioned on the firearm body for communicating trigger displacement information and/or firearm body motion information to the electronic device. Methods of providing firearm user input information to a firearm user are also provided.

A system and method for measuring, characterizing, and making recommendations for improving the performance of a shooter and one or more associated firearms. A data collection environment comprises an operator device and a server and data management module configured to receive and transmit one or more data sets over a network. A rig, which may be configured with sensors, may comprise a base assembly, a stock assembly, a grip/trigger assembly, a forend assembly a remote trigger assembly, and a safety lanyard assembly.

Devices, systems, and methods of manufacturing are disclosed with regard to a rapid-fire accessory that mounts onto a semi-automatic firearm using structural features thereof and/or added thereon to guide a trigger actuator for engaging a trigger and repeatedly firing the semi-automatic firearm. The rapid-fire accessory does not require the removal or replacement of the original, replacement, or aftermarket firearm grip or most other components of the firearm. The rapid-fire accessory provides a structural component an operator may hold that facilitates bump firing the semi-automatic firearm. Once mounted on the semi-automatic firearm, the rapid-fire accessory may slide rearward and forward, using a bottom rail on or below a forend of the semi-automatic firearm as a guiding surface and securing element. The rapid-fire accessory also includes a forward-hand grip for comfortably and securely holding the rapid-fire accessory steady, while the semi-automatic firearm is pushed forward and then recoils backward from discharging.

Systems, devices, apparatus and methods for providing a semi-automatic rifle with ammunition magazine, having a docking port/station for allowing a semi-automatic pistol to be inserted. The trigger on the pistol can be used to fire the rifle and use the rifle ammunition. When the rifle ammunition is depleted, the pistol can be removed and separately fired using its' own ammunition.

Devices, systems, and methods of manufacturing are disclosed with regard to a rapid-fire accessory for a semi-automatic firearm. The rapid-fire accessory may include a trigger guard mount, a trigger actuator, and a trigger guard adapter. The trigger guard mount may include a mounting channel for receiving a trigger guard. The trigger actuator may be fixed relative to the mounting channel and configured to pull the trigger when the trigger guard slides forward in the mounting channel. The trigger guard adapter may be configured to mount on and remain fixed relative to the trigger guard. The trigger guard adapter may include an adapter channel for receiving the trigger guard. When the trigger guard adapter is mounted on the trigger guard and in the mounting channel, the trigger guard adapter guides a sliding movement of the trigger guard mount forward and rearward relative to the trigger guard adapter and the trigger guard.
