Presented is a gas operated, semi-automatic rifle having a shortened barrel. For actuating a receiver to provide the semi-automatic feature, the rifle has a gas system including a gas cylinder assembly attached to the barrel at a second angular position relative to the barrel. For linking the gas cylinder assembly with the receiver, an operating rod is provided having a charging arm engaging the receiver and a distal end located at a first angular position relative to the barrel. The gas cylinder assembly and the distal end are hence coextensive to each other, eliminating the length of the barrel otherwise necessary to position the gas cylinder assembly and the distal end in a linear relationship. To provide for interaction between the gas cylinder assembly and the operating rod, an abutment block is attached to the operating rod and positioned at the second angular location.
