And good, quality match barrels are much more likely to have a concentric ID/OD. Some profile between centers, concentric to the bore after drilling/rifling.

Or just throw your muzzle adapter of choice on this gun as-is and use it. Threads concentric to bore and plenty of meat left to torque it down. No worries about baffle strikes.
Not ADCO's fault, and Stag isn't going to replace a barrel for that reason. Just shoot it! |

Oh I understand, and it's rarely an issue unless you plan on a suppressor or shoot longer ranges with a thin barrel. Turning a barrel between centers when profiling would eliminate 90% of these issues though. |

.......and now, for the rest of the story! That explains a lot, knowing the whole story. A couple things that cross my mind are.....I'm guessing the threads are of the correct pitch diameter, knowing Adco's reputation, so, I wouldn't hesitate to shoot the barrel with a flash suppressor of some sort screwed on. Second thing is, I don't know if I'd use it with a sound suppressor screwed on, even if it didn't have the eccentric major diameter of the threads........what's a "silencer" supposed to register to without a square shoulder. (I use the term silencer to differentiate between a flash hider/suppressor and a sound suppressor) For sure, you'd have to check very closely with a pin gage/rod to avoid baffle strikes.

All of this has reminded me
When I had my 20x102 threaded for a muzzle brake, it looks like they knocked the tops of the threads off, but in retrospect it might just have been the OD wasn't enough to thread to a point. Question: Is there a reason you would want to not have the threads taper to a point, but have flats? Very much like that offcenter side on that 300blk barrel. J |

Then turning the OD and cutting 1/2x28 threads would have been a better option (depending on the suppressor OP plans on using...and if a 1/2x28 mount is available in .30 cal ... ie....AAC has them for FAL's). Looks like ADCO acknowledged there was an issue and a mistake was made in shipping the product, but I'd still be pretty surprised if that showed up at my door. |

I'm sure the current threads would be fine for a flash hider, but I wouldn't bet a tax stamp on it if I had plans on mounting a suppressor. Moot point now since the customer has the barrel back, and STAG likely won't touch it since someone else worked on it. |

I try not to buy bad parts, the only reason I sent my barrel to adco is because of their reputation. I was shocked when I opened the box and saw it. I had no idea the barrel was out of spec. They did the right thing. I don't plan on using it suppressed. The barrel is a 6.8spc not a 300 bo. I had my first 6.8 dorms barrel cut and threaded wo problems and the have out of spec parts.

This is going to sound corny:
ADCO has done a reasonable amount of cutting, threading, and/or permanent mounting for me. Everything they have done was flawless. They have also stood behind other people's products that they have sold me. In one case Steve shipped me a RRA replacement hammer ASAP when the one I had purchased failed. I'm guessing that he made a special trip to the post office to get it to me when I needed it before a long three day weekend shoot. I can only say nice things about ADCO. |

However in this case, the threads are cut parallel to the bore axis. As a result the suppressor mount and suppressor will be centered to the bore axis, and no strike will occur as a result of the thread job.. |

It wasnt supposed to ship. It got threaded, then put into our "problem pile" The customer was supposed to have been contacted. I went out of town for a couple days, when i returned, i was told that barrel had already been shipped. I wish the customer would have contacted us about this but...... If you don't mind me asking (and I apologize in advance if this information was posted and I missed it): ADCO, I'm curious, did you make any attempt to contact the customer once you realized the barrel had shipped by mistake? Or did you decide to just wait to see if he contacted you? I'm just wondering how many other things shouldn't have gone out your door but did, or how many other times you should have contacted the customer but didn't. HKILLER, how much time passed from when they sent the barrel to when you posted? I'm just wondering if they had an adequate amount of time to contact you about the issue (if they really wanted to).

Ok so just to make sure Im following along:
OP buys a 2nd rate turd barrel and due to his lack of understanding about threading, requests 5/8-24 at the grenade notch. Adco completes the work as requested giving him a safe and serviceable product and althouth not pretty, it IS compliant with the OPs request, safe to shoot and improved from it's original form. Yeah, Adco sucks. |

Right on ADCO's order FAQ it says "WARNING - be sure you know what you are requesting. We will deliver exactly what you ask for, which isn't always what the customer wants."
ADCO delivered exactly what the customer asked for: 5/8-24 threads cut parallel to the bore axis in the undersized grenade notch of a poor-quality non-concentric barrel. It turned out that the customerdidn't want that, but he did ask for that, and ADCO makes it very clear that they will dogmatically deliver exactly what you ask for. |

That statement is not applicable to this situation. We will NOT proceed with a job if we know it will result in a defective product. That statement regarding "getting what they ask for" refers to contour diameters, barrel lengths, muzzle device pinning/removal, etc. As has been said many times in this thread, there was no way to know this barrel was off center until it was too late. |

I thought we put this one to sleep. First of all per adco stag is not a second rate company they adco advised me they occasionally get a bad barrel slip out. Second I contacted adco for advise for the barrel lenght a 6.8spc would run suppressed,they recommended 11.5. They had barrel about 20 days then it showed up at my door without any email, phone call or even a note in box. I went with them because of their reputation, I think they could have advised me about the issue. They appologized and made it right with me.

Your prior statements indicate that you knew the threads would end up in the grenade notch. At the very least, that much can be measured before the chop happens. Concentricity can't be checked beforehand but the chop point and major diameter of the grenade notch certainly can. You seem to think I am against you but I think you are misreading my post. I acknowledged that you turned correctly concentric threads in the area specified by the customer. That does not make the product defective in my mind; it makes it what the customer requested. You guys recently chopped a barrel for me but left the gas port untouched because I want to further modify the barrel. I asked for that. If I put it on an AR tomorrow it would fail to cycle, but that's what I asked for and I would have no right to blame you for a malfunctioning barrel. |
