Patent ID: 8371208

Claim:
A method for firing multiple rounds of ammunition in rapid succession from a semi-automatic firearm, said method comprising the steps of: loading a first round of ammunition into the receiver of a semi-automatic firearm, the receiver configured for chambering a round of ammunition and operatively connected to a barrel extending forwardly from the receiver and a trigger configured to selectively stimulate a round of ammunition disposed in the receiver, the receiver and barrel and trigger being moveable together as a firing unit; providing a handle adapted to be held by a user; supporting the firing unit in a forward pointing direction by the handle so as to enable reciprocating movement between the handle and the firing unit; stabilizing an actuator in a stationary position relative to the handle so that the firearm trigger will intermittently collide with the actuator in response to reciprocating movement of the firing unit; generating a primary forward activation force without spring force assistance urging the firing unit forwardly while the user firmly holds the handle so that the trigger collides a first time with the stabilized actuator; generating a recoil force sufficient to cause the firing unit to translate rearwardly relative to the stabilized actuator, separating the trigger from the actuator in direct response to the recoil force; automatically self-loading a second round of ammunition into the receiver in response to the recoil force; generating a secondary forward activation force without spring force assistance urging the firing unit forwardly relative to the stabilized actuator so that the trigger collides a second time with the stabilized actuator; and manually varying the intensity of the secondary forward activation force relative to the primary forward activation force to proportionally alter the firing tempo of the semi-automatic firearm.
