Patent ID: 8127658

Claim:
A method for firing multiple rounds of ammunition in succession from a semi-automatic firearm, said method comprising the steps of: providing a semi-automatic receiver for chambering a round of ammunition, 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; loading a first round of ammunition into the receiver; placing a user's first body part in operative relationship with the firing unit so that movement of the first body part causes a corresponding movement in the firing unit; stabilizing an actuator in a stationary position relative to a second body part of the user so that the firearm trigger will intermittently collide with the actuator in response to linear reciprocating movement of the firing unit; moving the user's first body part relative to the second body part using only human muscle power to generate a primary forward activation force urging the firing unit forwardly so that the trigger collides a first time with the stabilized actuator; stimulating the first round of ammunition in the receiver in direct response to said moving step, said stimulating step including discharging at least a portion of the first round of ammunition from the receiver into the barrel, said discharging step including 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; then moving again the user's first body part using only human muscle power to generate a secondary forward activation force urging the firing unit forwardly relative to the stabilized actuator so that the trigger collides a second time with the stabilized actuator; repeating said stimulating step with respect to the second round of ammunition in the receiver; wherein the improvement comprises slideably supporting the firing unit in a forward pointing direction by a handle for linear reciprocating movement relative to the stabilized actuator and the handle during said moving and said moving again steps, the linear reciprocating movement occurring along a constrained linear path generally parallel to the firearm barrel.
