Abstract
An electromagnetically variable firing system for a firearm is disclosed which may include a trigger assembly or mechanism comprising an electromagnetically-operated control device which allows the user to select and adjust the trigger pull force-displacement profile electronically. In one embodiment, the control device may be an electromagnetic trigger mechanism comprising an electromagnetic snap actuator operated via a microcontroller. The microcontroller is configurable by a user to adjust the trigger force-displacement profile according to preset user preferences. The microcontroller energizes the actuator during a trigger pull according to a preprogrammed trigger force and/or displacement setpoint aided by a trigger sensor(s). The energized actuator creates a magnetic field which dynamically increases or decrease the trigger force required to fully actuate the trigger to discharge the firearm. In other embodiments, the control device may be an electromagnetic magnetorheological fluid actuator.
