A little background...

Last weekend I was at Fort Dix doing a MG shoot with battalion. For those who are unfamiliar with how these things work, they are very, very serious about weapons safety, as we all should be. After the course of fire is complete, the weapons are visually cleared and then a SNCO will come through each weapon and stick a punch rod from the tip of the barrel all the way to the face of the bolt which is locked back to the rear. Upon visual ID that the punch rod is all the way through, the weapon is deemed safe. This is to show that without a doubt there is nothing in the barrel/chamber.

We were shooting the M240B, an open bolt MG. That means that, aside from the millisecond where the bolt is forward and the primer is being struck by the firing pin there is never a round in the chamber. That is to say that condition 1 is bolt locked to the rear and rounds on feed tray. When the trigger is pulled and the sear is released, the bolt rides home pulling the round down from the feedway into the chamber at which point it is fired.

Aaaaaanyway, we finished shooting at about 1930 on Saturday evening. We had a competition between the companies in which the MG section leaders were to determine who had to police call. A couple guns went down, one due to what I think was a firing pin issue. When they were done, the guns were cleared in the aforementioned manner and brought off the line. Personally, as we all should do, If I am taking a gun off the line I also check myself if the gun has been idle since the SNCO checked it, basic weapons safety. I happen to remember that I pulled gun 4 off the line in this manner.

Sunday morning, we are on the bus heading back to CT when my gunner behind me started to clean one of the 240s. He taps me on the shoulder and says "we have a big issue here". my immediate thought was that he had left a piece of gear somewhere. What actually was the case is that there was a round in the chamber that he noticed as he was cleaning it. This means that from 1900 until about 0930 the next morning there was a condition 1 weapon that no one knew about. Im still trying to wrap my head around how this could have happened. The only 2 things I can imagine is that

1) After the firing pin issue, a barrel change occurred improperly, in which the barrel was changed with a round still in it. Then later, off the line, the barrel was swapped again, with the spare barrel that had the round in the chamber. (on the 240 the chamber is in the barrel).

2) Someone intentionally out a live round in the chamber... god knows why....

This is the worst case and closest call I have witnessed or even heard of in my 3+ years in. Worst case is scenario 2, which I highly doubt is the case. But even if it is scenario 1, we have some new joints or even experienced guys who have some serious, serious weapons safety issues.

I still shutter to think what could have happened. If that bolt was to the rear, which it probably was, it could have fired if it was dropped, kicked etc. If my gunner didnt use proper weapons handling procedures and sent the bolt home without checking that thing would have definitely gone off.

scary shit

Was the primer dented? if it was a firing pin issue it may of left a small dent and not discharged the round. That would tell you the above scenario or something close to it happened. To get a round in the chamber you would really have to try. IE lift cover lift feed tray pull bolt to the rear and stick your hand in there.

In the end no matter what this was a failure to fully clear the weapon, props to your gunner for doing the right thing.

Have you inspected the firing pin? and the mount for the pin on your return rod?
your -10 should cover it.

If this is the worst you've seen "You aint seen nothing yet." Good luck :)
 
primer wasnt dented, first thing I checked. I think the issue was we were very short on CLP at the time and it was not operating well. Possibly causing the momentum of the bolt to be decreased enough to prevent firing. That being said, it would still have dented the primer.

Not really a weapons safety situation, but I have had a ma deuce blow up in my face before, took a piece of the receiver to the cheek. Hard to explain what happened, but the battalion gunner was even surprised by it.

Head space and timing most likely.

You're very lucky. I went to Vilsecks sam-31 and they have pieces of a M2 barrel on their wall that killed the gunners team leader at a range. They were using the weapon without checking head space and timing.
 
not H&T, during extracting when the bolt was sent to the rear it splintered into the receiver rails. There was still a round in the chamber at the time. We knew that but had very few options to get it out. The bolt literally cut into the rails and when we finally knocked it loose the thing just shattered.
 
Ahh could be just alot of wear and burrs in the reciever not kept in check.

Their are alot of old .50's still in service.

My serial was in the 2000 area, old as dirt , though I'm sure it was refurbished a time or two :)
 
holy hell. Theres a picture out there somewhere of some army guy banging out the pin on the gun mount with the primer end of a .50 round. Took off his hand minus his thumb and pointer finger. The stupid part is he had a rock or something first then decided that a round would work better....
 
I'd post the .50 cal hammer pic but I don't think it's family friendly :P
 
K I'll dig it up


Edit: dug it up I don't think it's even den friendly lots of tissue and things not in the right place.

WHILE MOUNTING THE M2 MACHINE GUN ONTO THE TURRET SYSTEM OF HIS MATV DURING PRE-COMBAT CHECKS, THIS SOLDIER EXPERIENCED DIFFICULTY INSERTING THE LOCKING PIN ON THE MOD 93 MACHINE GUN MOUNT. THE SOLDIER THEN ATTEMPTED TO FORCE THE LOCKING PIN INTO PLACE WITH A ROCK. AFTER THIS FAILED, HE THEN SECURED A LOOSE .50 CAL ROUND, USING IT TO HAMMER AT THE LOCKING PIN
