Ok a buddy and I are debating on whether it will hurt the M4 to shoot 10 tracer rounds in a row. Right now he was his mags filled with 10 ball, 10 tracer, 10 ball. I was like you should switch that up and put 3 balls to 1 tracer so your barrel doesnt get to hot. He was like no it will not hurt the barrel to run 10 tracers in a row. So my ? is will hurt to run 10 tracers in a row?
