The barrel, bipod, grip assembly, railed top-cover and hooked buttstock all look consistent with a U.S. Ordnance M60E6 rebuild kit, but they kept the older style straight forearm.
1) Grasp, pull, and hold the cocking handle to the rear. This blocks the operating rod assembly and bolt assembly from cycling immediately. If possible, lock the bolt to the rear, place the weapon on safe, and analyze the failure.
2) Grasp and twist the ammunition belt near the feed tray, stopping the feed. Attempt to lock the bolt to the rear, place the weapon on safe, and analyze the failure.
3) Grasp and twist the belt to break the belt near the feed tray, allowing the remaining rounds on the tray to cycle. Attempt to lock the bolt to the rear, place the weapon on safe, and analyze the failure.
4) Keep the weapon pointed in a safe direction (downrange works just fine) and wait for the ammunition to run out. Attempt to lock the bolt to the rear, place the weapon on safe, and analyze the failure.
#4 is easiest when there are only a few rounds left in the belt. If there is a long belt, or you need to stop the weapon from firing RIGHT FUCKING NOW, use #1, #2.
I think what I found most troubling was that: 1) the person firing was allowed behind a live weapon without having been taught any of these things. 2) The instructor missed a perfect training opportunity to look down at the firer and say, "Well? What're you gonna do now, Ranger?"
Most common causes can be, but are not limited to: 1) a broken or worn sear (most common) 2) a broken or worn sear notch on the operating rod (less comnon but does happen) 3) the operating rod is recieving just enough gas to drive the bolt back just far enough to pick up the next round on the feed tray, but not quite enough to engage the sear. If so, this can be corrected immediately with a barrel change. 4) Debris in the action preventing proper function of the sear.
On the Mk19, just grab either cocking handle and pull to drop it down into the cocking position. This will stop the sear from releasing the firing pin, firing the weapon, and stopping the cycle.
