• said trigger having a hook portion adapted for engagement with a ledge portion of a rotationally mounted hammer communicating with a firing mechanism of said AK-47;
• said hammer rotatable from a cocked position to a firing position activating said firing mechanism by a means to bias said hammer to said firing position;
• said trigger having trigger lever;
• said trigger having a slot formed therein sized to accommodate a disconnector;
• said disconnector rotatable upon said pin from a first position to a second position closest to said trigger hook portion;
• said trigger having an engaged position biased toward said disconnector with said hook portion having a surface engaged with a ledge on said hammer thereby holding said hammer in said cocked position;
• an adjustment screw translateably engaged in said trigger at a position behind said lever, said adjustment screw adjustable to protrude varying distances from said trigger thereby providing a means for adjustment of the amount of surface of said hook portion engaged with said ledge;
• means to bias said disconnector to rotate on said pin toward said second position;
• and
• said trigger moveable from said engaged position to a disengaged position by application of force to said trigger lever thereby rotating it upon said pin and disengaging said surface of said hook position with said ledge, wherein pulling said trigger lever with a finger will disengage said trigger from said hammer allowing said hammer to rotate and fire AK-47.
