If you’re having to mortar it to get live rounds out you have bad ammo or a bad chamber.

I don't know how I missed this!!! I'm sorry for the late reply, we will absolutely help. Please hit us up at the shop and our CS folks will make sure you are taken care of and your upper is good to go. We'll get you set up with an RMA to send it in for us to inspect and make sure you are taken care of.

Little bit of an update. Got in touch with Geiselle, nothing beyond the "what happened" email. Figured I'd see if the issue persisted, so I went to the range this morning. Started off with a brand new Pmag and the same ammo. Once again the upper completely seized up. Zero movement whatsoever. The bolt appeared to be unlocked but would not move whatsoever. Next I tried the same ammo through a Colt, BCM and 14.5 URG-I, all ran flawlessly. Later in the day I tried switching the Super 42+H3 the upper came with for a Sprinco Blue + Spike's T3. Only put 30 rounds through that set up, but, it worked. Mostly. I say mostly because occasionally the BCG occasionally wouldn't strip a new round out of the magazine and I'd have to manually charge it.
Not posting this to bad mouth Geiselle, but more so to keep the thread alive in the event someone: A) Has some answers/resolutions to my issues or B)Someone else is having similar issues and can't find any information. |

H3 is a little much for an 11.5” barrel with a .068 gas port, I’d try an H2/ H1 buffer with the sprinco blue.

Using the super 42 and H3, do you think there would be any relation to the upper seizing up?

So when this issue would occur, it would become a failure to feed. The round would eject, strip a new round and then stop just shy of closing. The BCG would seize up about a 1/4" from full battery. Does this sound more indicative of a bad chamber? I'm running through as much bro science as I can to figure out why it would only happen with the S42 and not a Sprinco

Please take the upper off the lower.
Hand feed a round into the bolt and feed it into the chamber. See how hard it is to go into battery. Push the carrier in and see if it fully chambers. The reason I mentioned feed into the bolt is to get past the part where the extractor has to jump over the case rim. Then come post what happens. If it doesn’t work. Something else is going on and the upper will likely need to go back. |

Quote History Quoted: Did this and sure enough, the bolt wouldn't close. Do you know what issues could cause this? There are a few issues that could cause this. Bulge right answer is simple. Talk with GACS and send it back. They will make it right. I have ZERO doubt on that There is something in the path of the cartridge. Looking into the chamber may not tell you much as it would only take something being off a few thou. (.002 of an inch) to really F your day up. If you were near me I’d happily offer to look and take some measurements of the chamber and put an educated eye on it, as well as throw some chamber gauges on it. Please verify one last thing. You did have the cartridge UNDER the extractor when you tried the test. If you are having a hard time doing that. You can also remove the bolt and remove the extractor from the bolt to make it easier to do. You’ll just end up having to use a cleaning rod to tap the round out and things get more complicated then if the cartridge got stuck. If you’re having an issue understanding what I am trying to convey send me an IM and I’ll send you a phone number and can walk you through the process over the phone. NachoDip |

Did you clean the chamber and locking lugs ?
You previously stated it ran fine zeroing it. Pull the bcg and examine the locking lugs. Brush them clean. Check to see how freely the bolt moves by hand. It should rotate easily with no hang ups. One tiny bit of brass or lead or nearly anything hard in the wrong place can cause issues. Including burned and unburned powder deposits. First course of action is clean the shit out of it so you know you are starting with clean surfaces. After that chamber a round. Un chamber the round and look for scratches and deformation on the case. |

Un chamber the round and look for scratches and deformation on the case. Upper was cleaned thoroughly after the initial trip and the problem persisted every subsequent outing. It took me five rounds to zero so I don't think there was enough volume for the issue to present itself. From where I'm at now, I'm just going to wait for a response. I'm already down a B5 sopmod from mortaring this thing trying to unlock it the first time. The last thing I want to do is damage something else. |

Take the upper off the lower, take the bcg out, drop a round in the chamber.
It should slide out. |

I was one of the first people to get one of their new barrels (11.5) and it’s been perfect. No ragerts. I just need to find the Surefire washers to time the Surefire flash hider. Barrel hasn’t been shot for accuracy. It’s an 11.5. It functions and cycles nicely with good quality parts. It’s got about 1000rds down the barrel so far. |

I had this exact problem with a brand new 16” Super Duty upper despite scrubbing the chamber and all that good stuff prior to ever firing it. Had to have the barrel replaced. The guys at CS were super helpful, I would recommend calling them in addition to the email as they were very responsive on the phone.
They paid return shipping and everything. Only complaints are it took about a month to get it back, and didn’t do anything about where I scratched the crap out of my CH mortaring it to get the love round out of the chamber before warranty work. The new bbl is 100% so far and shooting sub MOA (though haven’t shot past 50 yds yet). The frustrating thing is this could have been 100% prevented by test firing the upper prior to shipping. I hope that is something G will consider adding in the future as test firing/QC is a big part of what separates the higher tier manufacturers from home builders and lower to mid tier stuff. Just doesn’t make sense to me to make a $1200 upper and not test fire it. Overall, pleased enough that I will likely be ordering a 14.5 pinned to work in tandem with this one. Disappointed to know that others are having the same problem though. |

I’m in the same boat with a brand new 16” super duty doing the exact same thing. CS has been very helpful. I’m hoping to get mine back in the mail to me by the end of the week, per Justin. We’ll see.
My charging handle took a beating as well and it shows. Mortaring wouldn’t work on my rifle. I had to take a rubber mallet to the CH to get the stuck cartridges out. |

I bought an 11.5 SD just before Memorial Day and finally shot it yesterday. I got about 3/15 rounds fired. My guess is the chamber is out of spec because of the way the rounds were failing to feed with multiple mags and ammo types. Had initial responses from CS but its pretty apparent that G doesn't test fire and they really need to.

I am having same issue with a 11.5 URGI near clone that I bought on sale over Memorial Day weekend. Called Geissele today at dinner they told me to go online to do the RMA process. I too was figuring it must be something wrong with the chamber dimensions but honestly super surprised to have encountered this with a high end upper.

Glad I found this thread and confirmed I'm not crazy. Same issue with a 11.5 barrel I ordered in May and Received in June. About 1 of 10 rounds of xm193 I had to mortar out. Prvi 75gr were 0/3, had to mortar all 3 of them out. Rounds stick in the chamber drop test and have to cleaning rod them out. Will do the needful.

I’m still waiting to get mine taken care of. I sat on it for like 3 weeks as I was in the process of moving but have traded a number emails back and forth, trying to get them to send me a UPS label so I don’t have to pay to send it in. They’ve responded every time but it usually takes a couple of days and I was supposed to get the label from UPS in an email today apparently but nothing yet. I’ll hit G up tomorrow about it, I am a bit surprised I haven’t gotten lost in the shuffle with all of the back and forth.
Edit - I was wrong, it went to a different email… |

Got mine back a little while ago. Went to test it out and had the same issue on the first round. Every subsequent round after fired, extracted and ejected as it should. Only shot about a mag's worth though. I'm still a bit hesitant to rely on this thing. Didn't receive any information detailing what was done do remedy the issue.
