A weapon system is provided. The weapon system includes a receiver and an operating group. The operating group includes a bolt at least partially housed within the receiver; an operating rod (op-rod) assembly arranged to axially translate within the bolt. The operating group also includes a carrier assembly, a bolt assembly, and a recoil assembly. The system further includes a hinge or pivot joint at a connection between the recoil assembly and the carrier assembly, a firing pin lock, an elastomeric cone interface between the bolt assembly and the receiver, a hollowed out piston, and/or tapering on the lug of the bolt assembly.

A trigger bar for a semi-automatic firearm. The trigger bar includes a longitudinal body with a rearward lateral arm. The arm includes surfaces for engaging the sear and the drop safety lifter of the firearm. The surfaces are configured to reduce trigger pre-travel distances by reducing a trigger travel distance prior to drop safety lifter engagement, sear engagement, and striker release. An over-travel stop reduces a trigger over-travel distance.

A multi-projectile launcher capable of firing less-lethal 40 mm rounds or high explosive 40 mm rounds (i.e., HE Grenades) can be attached to robots, drones, vehicles and stationary structures. The robot/drone multi-projectile launcher is remote controlled and capable of 360 degree horizontal rotation as well as vertical panning, and is able to quickly turn and acquire targets. A solenoid controlled firing system for each barrel includes a firing pin, trigger lever and striker, as well as a lockout bar and striker seer to prevent accidental firing (e.g., from impact or sudden jolt). Target acquisition systems include an infrared laser system, a standard red laser system, and an optic targeting system that is monitored through an onboard camera. A wireless network access device allows for remote viewing of live-feed camera images (still frame and video) and control of the optic targeting system, as well as the launcher articulation and firing.

A modified trigger assembly for a handgun has a shortened trigger bar with an angled end that engages a connector to form a gap that reduces potential energy between the trigger bar and the connector, such that the connector is inhibited from disengaging from the trigger bar when the trigger is pulled or released. A gap forms between an angled end of the trigger bar and a first end of the connector. The gap and the shortened length of the trigger bar reduce potential energy forces that could disengage the connector from the trigger bar. By remaining engaged with the trigger bar, the connector is prevented from resetting to a natural position; and consequently, the handgun can discharge from both a trigger pull position and a trigger release position. Consequently, a repeated shot occurs when releasing the trigger after a natural triggering movement of pulling a trigger.

A pistol has a frame with a striker operably connected to the frame. A trigger is operably connected to the frame. A transmission element is operably connected between the trigger and striker to motivate the striker to discharge the firearm in response to actuation of the trigger. The transmission element is movable between a first position in which operation connection from the trigger to the striker is enabled, and a second position in which operation connection from the trigger to the striker is disabled in response to acceleration forces due to dropping the pistol.
