A gun team with Alpha Company, 1st Battalion, 75th Ranger Regiment change the barrel on a M240 during a training exercise. A M240's barrel will overheat and eventually melt if too many rounds are put through it in too quick succession. A M240B is issued with a spare barrel which can be quickly swapped out in the field. When used in rapid fire mode - 200 rounds per minute fired in 10-13 round bursts with 2-3 seconds pause between burst - the barrel requires changing every 2 minutes.
