That's wild. I'm gong with the following. 1. Obstruction 2. Weird shit happens 4. Pressure spike due to...? 3. Something went wrong in the forging process. I have 5 DD rifled barrels with plenty of rounds through them, they are excellent barrels. However unlikely that it was a barrel issue, every manufacturer has had a part fail here or there on a customer's rifle. I'm sure DD will take care of you. I'd guess 3. with the possibility of 2. I would not choose 4 due to the fact that it is in the wrong order.  Seriously though, that is a very strange place for a failure. The majority of pressure is in the chamber and decreases as the projectile travels down the length of the tube. The OP may have the very first legitimate bigfoot sighting.

Has the weapon ever been rapid fired in semi-auto; fired in this fashion has the barrel ever been possibly overheated?

First I think its a pressure made fracture and could this be possible..gas block obstruction/gas block movement over the gas port causing a high pressure curve?..in any event I think its pressure related and because of where it fractured the only culprits for over pressure forward on the barrel is the can.gas block,gas port...my .02

If you really think it blew because the gas port was blocked or too small then you would see bolt guns exploding all over the place. Those don't have gas ports AND don't have an open chamber after the round is fired.
There had to have been an obstruction in the barrel. The only relation to the gas block is that it held the barrel together at that point and kept the splitting from going further towards the chamber. |

If DD doesn't replace that I'd be shocked. It shouldn't matter if he's got a suppressor or not on it, your barrel shouldn't split open.. lucky, your hand couldve got shredded

I have yet to see one split the barrel. Now, if there was some sort of flaw around the port (far fetched speculation) then I could see it starting there, from some sort of gas obstruction. I am hedging on the barrel obstruction theory. |

My guess:
There was something sealing the barrel, perhaps even water or vapor in the silencer. Bullet is fired and begins to travel. Bullet creates pressure behind obstruction, barrel splits behind obstruction because silencer doesn't allow the pressure to dissipate fast enough. Silencer holds threads of barrel together. Bullet has been stabilized and continues to fly fairly straight despite new "crown" and exits the silencer without striking or damaging it. The reason the barrel only split in front of the gas block is that the gas port allowed some of the pressure to travel into the gas tube and dissipate. |

Quote HistoryQuoted:
"There were three splits in the barrel, starting past the gas block, and almost to the threads on the end." I'm no expert but it appears the gas port diameter was not sufficient to run the suppressor long term. The number of rounds previously fired without incident, the three(3) splits and their location seem to indicate this. I have a couple of questions; 1) Does a suppressor that's threaded on the barrel create more pressure than one attached to a mount? 2) OP, which suppressor? It is a Huntertown Arms K-556 |

I don't rapid change magazines, and put 300 rounds at a time through it. I tend to be a deliberate shooter, as I am more into accuracy than speed. Disclaimer: I would still love to get a hold of a minigun, even if only for 10 seconds of fire

The reason the barrel only split in front of the gas block is that the gas port allowed some of the pressure to travel into the gas tube and dissipate. Best theory to me so far. Barrel only spilt enough to release the pressure and the bullet kept flying. If the bullet hit a squib, the damage would be worse IMO. Gas block obstruction is nothing. How do you think people make single shot ARs. They don't all order port less barrels. Plus the thinnest part of the barrel is under the rail before the gas block. You would think if the whole barrel experienced the pressure spike then the failure would have occurred there (in theory). |

Quote HistoryQuoted: I always inspect down the barrel prior to shooting. There were no obstructions that I saw. I didn't clean it after the last time I shot, and my OCD was killing me a bit on that one. I only ran 100 rounds through it last time, and no issues. The explanation given at the store was the best I could figure. He said it is rare, but there are double powder rounds that come out, maybe 1 in a million. That, combined with the can on the front, could have caused it, with a weak barrel. Sounded like a perfect storm scenario to me, but anything is possible. I bought from DD, due to their reputation. I hope I am not let down. It has been a rough few firearm months. I also own a Springfield XDs (no I am not complaining about the recall). Let's say I am just glad no one has gotten hurt, and there are two empty spots in my safe waiting for these two to return (among the other empty spots for future additions). I will let everyone know as soon as I get a response from DD. Quote HistoryQuoted: Quoted: I just can't get over how it happen so far down the barrel. You said it was your first round of the day right? So I pose this question, don't take offense. Did you inspect the rifle after you last took it out or before shooting it this time? Possible squib from last range session maybe?? Assuming you did nothing after or before this range of course. If you did... then my mind is blown. Only explanation i can think of is weak spot in barrel finally gave out brother. Bad/Good luck all in one. Let us know what DD says. I always inspect down the barrel prior to shooting.

I will let everyone know as soon as I get a response from DD. You certainly encouraged me to change my checklist. I never check the barrel for obstructions, instead I rely on my cleaning procedures to ensure that I don't flake out and leave a patch in a barrel. But one can never be too safety-conscious. I'm glad you're safe, OP. FWIW, I'm guessing that the suppressor played some role in this mishap, perhaps, as was suggested above, by increasing pressure enough to expose a flaw in the metallurgy. |

Again, the suppressor does not and can not increase the pressure in the bore.

I have a theory. I had a thought on whether you run the suppressor wet or dry.
Reason being you hadn't cleaned the gun since the last time. you checked for obstruction before this shoot and everything was ok. You added your water, oil, grease etc. to the suppressor and ran it after. Since you hadn't cleaned it the sludge from the suppressor runs down into the barrel. your first shot meets the sludge splitting the barrel. Theory only works if you run wet, otherwise i got nothing. |

Just to keep everyone in the loop:
I have received several e-mails from Joe (DD Rep). He got me in touch with someone in Customer Service. She called me, and has assured me that the turnaround on my rifle will be extremely quick, as I live only about 4 hours from one of their facilities. It may take them a week or two to get us all the answer to what could have caused this, but she did let me know that it was extremely odd where is cracked (as we all already know). They are also interested to know what happened. I will let you all know the outcome, and how quick the turnaround went (I am sure it will be as fast as possible). |

Glad you weren't hurt.
I too have an early model DDM4v5 that I run suppressed, tagging for follow up. First shot of the day and location of damage makes a me lean towards a barrel obstruction, but I would think your can would likely have sustained damage, which it didn't. Joe is good people and DD CS is top notch, hope you get it all worked out quickly. |

Boy this whole thread feels like someone made an oopsy and wanted to get DD to replace the barrel they blew up with a squib they shot out to see what would happen.
I have seen a few rifle barrels split towards the muzzle like that and every one of them was caused by an obstruction. I look forward to the DD findings, I am amazed they are just replacing the barrel then figuring out what happened. |
