Abstract
A safety mechanism for a firearm includes a cam selector, a lever, and a trigger. The cam selector comprises a first end, a second end, a top side, and a bottom side. The cam selector comprises a longitudinal slot positioned on the top side of the cam selector. The lever comprises a proximal end and a distal end. The longitudinal slot is configured to receive the lever. The cam selector further comprises a first recess and a second recess on the bottom side of the cam selector. The trigger comprises a first trigger tail portion. In addition to the standard semi-automatic and safe modes, the present invention provides an additional active reset mode in which the cam selector is configured to allow the first trigger tail portion to engage the second recess and be moved down by a cam portion of the second recess when the cam selector rotates.
