Rapid-Fire Accessory Trigger Actuator for Semi-Automatic Firearms

The patent introduces a bump fire accessory as an intermediary device between the operator and the firearm trigger. This accessory includes a trigger actuator that automatically engages the trigger when the firearm is pushed forward, eliminating the need for the operator to manually coordinate trigger pulls with recoil movements. The accessory mediates the interaction by converting the natural recoil motion into automatic trigger activation, thus achieving rapid fire while significantly reducing the skill requirement.

The bump fire accessory enables the firearm system to service itself by automatically utilizing its own recoil energy to actuate the trigger. The trigger actuator is designed to be engaged by the natural rearward movement of the trigger guard during recoil, creating a self-regulating mechanism that consistently produces rapid fire cycles without requiring external intervention or precise operator timing. This self-service mechanism ensures operational consistency across multiple firing cycles.

The patent segments the rapid fire function into a separate, dedicated accessory component that attaches to the firearm's trigger guard. This segmentation allows the complex automatic trigger actuation mechanism to be isolated from the main firearm system, making it easier to design, manufacture, and operate. The accessory can be independently optimized for its specific function of converting recoil motion into trigger activation, while the rest of the firearm remains unchanged, thus reducing overall operational complexity despite adding a component.
