System for a Retrofit Trigger Actuating Mechanism Integrated Into a Semi-Automatic Rifle

Abstract

The system for a retrofit trigger actuating mechanism integrated into a semi-automatic rifle alters the dynamics of the firearm and allows for a higher firing rate. More specifically, the retrofit apparatus divides the semi-automatic rifle into two regions that are slidably coupled and thus allowing for the user to utilize a bump fire technique. The relative motion of the two regions allows for the trigger to be pulled, re-set, and pulled once again in a sequential manner yielding a higher firing rate when compared to standard semi-automatic rifles. During the sequential firing the user keeps the firing finger in a set position without any movement; the trigger is pushed into the finger to initiate the firing sequence each time. The components of this system do not require modifications for the rifle and may be integrated quickly and easily.
