I wish I did a search on Dead Air QC before taking the plunge. There seem to be a few older threads on this (now archived).
I bought several at once including a Ghost 45 M. Took it out for a spin not too long ago and out of the box was shooting low and left. Like, hitting the ground from 10 yards. Anyways, no baffle strikes, thankfully, with 9mm rounds. I finally got around to getting an alignment rod (of sorts) to check ... Definitely not a "tuning" issue. It's noticeably misaligned through the first baffle stack so back to the factory it goes. Bummed. https://www.mcmaster.com/ground-rods/tight-tolerance-multipurpose-oil-hardening-o1-tool-steel-rods/ |

On what platform?

I smell user error. Or bullcrap.

That's quite the feat to curve the bullet. I admit, if I had a can that could do that I'd probably market it for shooting around corners. Your move, Krummlauf. |

If you are putting a lot of effort into arguing with me, you are probably really just wasting your time, sorry.

View Quote yeah i sent pics to DA and the service dude didn't think there were any baffle strikes. however, i think there was some clipping on the wipe at the end of the wipe tube. i'll post pics in the am. |

just re-posting for later.
https://www.ar15.com/forums/Armory/Dead-Air-QC-Issues/20-511652/ never had any problems with mis-alignment on several other rifle, pistol, and smg cans (direct thread). this would be the first. |

View Quote This doesn't really make sense. A wipe by its very nature touches the bullet so there will be contact. Any contact with the bullet after it leaves the barrel is going to affect point of impact and accuracy, significantly. Anyone who cares about where their bullet goes does not use a wipe. This may be part or all of your problem but to me you sound a bit confused about how your suppressor works. For sure post a photo of the alignment since it may help. |

Anyhow,
What a PITA. Is it the barrel, the piston, or the can? Do I have to shell out more $$$ to get another barrel and piston to figure that out before calling the manufacturer? (think i figured that out already) Higher price + 12 month wait = higher expectations, right? With the crush of orders for cans from much shorter wait times, I kinda wonder what will happen to suppressor QC for everyone when manufacturers ramp up production to meet demand. Alignment rods are worth the investment - use 'em I guess. |

Absolutely, contacting the manufacturer is better than listening to me. So it looks like you may have a bad alignment right there, is that alignment consistent in relationship to the barrel when you have the suppressor assembly attached? You can try marking the piston (and the barrel if needed) and check put the silencer on (like with a sharpie marker), but if remains constant it would seem the problem relationship would be between the shoulder of the barrel and the shoulder of the piston. If you mark both the barrel and the piston where they closest and then put some shims (that are flat) when the piston is rotated, if the deviation remains the same in relation to the barrel, then it may be the barrel shoulder is the culprit. If the deviation or offset shifts with the piston, then it may be the piston shoulder that isn't true. Although camera pics can distort the view through angles it looks like the area I marked red is closer and green is farther. Maybe your dealer or someone near you has a different barrel you can try it on? |

Thanks guys. I broke out the nail polish and did not just a 180 but the full 360 "tune" of the piston vs. the tube.
No joy. The alignment rod is still hugging the baffles in each position. Will try to find a friend with another 9mm threaded bbl before sending it back. |

I just got it back.
It took like 5 days to get there fedex ground but they did a one day turnaround. I haven't taken it apart but it looks like I got a brand new set of baffles, both in the main and wipe module. I don't think the wipe is there any more. No pics yet but baffles are copper-colored, looking from the outside. Got a nice 15% off coupon for the site as well. Back to the range. |
