Why does this .50 gunner need to keep pulling the charging handle?
edit: Looks like his shit is jamming? I always thought the M2 was pretty reliable. https://www.youtube.com/watch?v=kiA_W9-pW9Y&t  50 Cal Gunner Engages Taliban Positions During Ambush |

I'm not ex/current military, but I would assume because it's not timed correctly.

Maintenance is lacking, and it sounds like the timing is off based on the sluggish operation. No excuse to not have proper H&T. It literally takes just a couple minutes for a properly trained gunner.

Thats what shitty headspace and timing will do. There are go/no go gauges for a reason.

Back when timing was an operator and not armorer task, it was pretty common.
Had a squad leader tell me not to waste my time with the ma deuce, but little did he know, I actually knew how to properly time it. 200 round burst happened immediately following his comment. |

At :52 -
Is it jamming? What? Is it jamming? Yes! It's probably jamming. No gun is reliable if it isn't properly maintained. |

just Monday morning quarterbacking as a former machinegunner...
improperly set timing (you should check with a headspace and timing gauge on the 50 every time you set it up) not enough/no lubricant poor maintenance or...just worn to shit. pick your evil. |

there's a slim possibility it's shit ammo also.
Never really saw that with the M2, but for what ever reason when I was in the Corps, certain batches of 40mm HEDP for the MK19 were garbage and caused lots of jamming. |

A lot of guys will run their gun without enough lube because they are afraid of grit advereing to the lube. A lot of worn out beat to shit .50s out there. At one point circa 2006 units were leaving behind some or all of their M2HBs for the unit replacing them. Guess which ones they left?
I had a gun blow up in my face on a range at FOB Falcon that had wood space grips and a wood charging handle. It was either that shitty IWI ammo there was problems with or the latch was worn on the 80+ year old gun. |

I remember getting training on headspacing and timing the .50 in AIT in the 70's
It's a simple machine, but it does need a little TLC to run right. |

Sluggish firing.
Possibly timing set too late, but more likely improper lube, or worn out/oil contaminated buffer disks. Adding a little clp to the feed lever track isn't going to cut it. You have to get the clp down between the bolt and barrel extension. Or it was PMJ ammo. |

Some guns blew from IWI/PMJ though because you could cheat and set the timing too early to try to get that shit to run better, but sometimes people went to far and their luck ran out. |

Not a slim possibility at all. Whole lots of Tawainese and Israeli .50 cal were suspended for QA issues like hard primers and hot loads. Israeli and Spanish were the crap. |

Burnt through a can melting buildings we were getting sniped from, and tossed the next can in and they wouldn't de-link. No other lot numbers either after trying a few other cans. 
Fortunately I got the one that was snapping rounds on me with the first can.

As far as the video goes could be a lot of things no way to tell just by watching. As far as the comment on sluggishness above that does not mean timing. If you remove the back plate you will see a notch on the back of the buffer this is used to adjust fireing rate within a small margin. |

When did headspace and timing become armorer lvl? Timing is locked, and armorer adjustment only. Barrel is inserted and rotated 60 degrees to lock in place. No operator adjustable headspace anymore. All the guns will be upgraded in the next few years. The USMC and Navy has also started upgrading their guns. Eta: The adjustable buffer hasn't been made since Korea, but they may still be used until replaced by attrition, and there are still a lot of them out there, but the majority of guns will not have it. |

How come it doesn't cycle a round out when he pulls the charging handle. I know it's normal, no fifty does, but why is that? What exactly happens in there when the CH is cycled?

I agree it sounds slow, so probably late timing.
But if you watch the charging handle when he releases it and listen to the gun shut on charging, that thing is either full of crap or has no lube. That you can hear how slowly the thing returns to battery. |

It is stopping with the bolt jammed to the rear, that is why it does not cycle out a live round. When it runs sluggish like that it jams in one of two ways. Either the spent case is not pushed out of the T slot fast enough, and the neck has jammed against the bottom of the barrel extension, or the next round is not pushed far enough down, and the nose of the bullet hits the back end of the barrel on top instead of feeding into the chamber. Either way you only need to pull the bolt back that last inch and let it go and the jam clears.
