Then take the shims out, tighten the MD and see if the orientation is the same or not. If the misalignment goes away, it was obviously the shims. If the misalignment stays with the orientation of the gun (for example, it was at 5 O'clock before and remains there with the gun in the same position), it's a canted muzzle shoulder. If it moves, it's something else. At that point, your ability to play the diagnostic game just depends on how many other hosts/mounts/muzzle devices you have around to play with, and whether or not some of them are known-good combinations. I do spin every one of these between centers on my Hardinge HLV and face the rear mating surface of the can as the final operation before moly resin, but unless the adapters AND the muzzle devices are sent with them, I cannot put everything together and spin it onto a fixture to check for runout in the entire assembly. You have 6 mating surfaces in play with most adapters, and I can only verify one of them without those other bits. If I have your adapter and your muzzle devices, then I can check 5 of 6. Need the barrel for the last one, which is generally not practical. If you still want to use shims to index the muzzle device, just make sure they're not getting crushed or otherwise deformed. Thin shims getting smashed/torn and squeezing out on one side of thinner barrel shoulders definitely happens. Also, unless you have a large granite table to roll it on, don't put undying faith in alignment rods being perfectly true. Many aren't from the get-go, and it doesn't take a lot to tweak thin rods, even hardened ones. The rods I use to indicate bores for muzzle threading are a lot shorter, and they still get spun between centers with an indicator before use, and they do get tweaked sometimes just from inserting and removing them. Trust your eyes; look through the bore from the breech end with a well lit light colored background, it's really easy to see can misalignment ahead of the concentric rings your chamber mouth, shoulder, throat and bore create. |

I've got a complete Surefire shim kit that has the beveled washer first....I'll try a few combinations and report back. |

So I tried the suppressor on a Larue rifle that has the Xeno brake. Perfect alignment.
Back to the MK18, I pulled the shims and cleaned everything. Tried the Xeno flash hider with no shims and still bad alignment. Then tried the Surefire beveled washer and it’s still off, just maybe not as bad. Attached File Then I loosen the suppressor and very slowly tighten it back on the muzzle device just till it’s snug. Perfect alignment! What am I chasing here? Attached File I’m thinking they Xeno muzzle device may be the culprit? DD barrels are not typically known for causing these types of issues I’m sure. |

I removed the suppressor and re-installed multiple times and the results were repeatable. so maybe it was the barrel shoulder. |

I had Nick do one of my Cyclone's. (I have 2) I am very happy with how it turned out. I run Cherrybombs on most of my rifles and wanted the ability to swap it around on some of my smaller caliber rifles. He did the omega "universal " thread with his own cherrybomb adapter.
One thing I wasn't aware of before I sent it in was the 1st blast baffle had to be removed to fit the Cherrybomb. weight before and after conversion. Before = 653g, after 657g (with adapter installed) Gained only 4 grams... |

The YHM QD system is a good one, most folks do the conversion to consolidate to another mounting system shared with other cans, or sometimes to go direct thread because they don't want a muzzle device on their host for unsuppressed use. |

The KAC QD I'm completely unfamiliar with. The usual course of action for making Bravo pattern adapters for QD mounts which don't exist is harvesting the mount from a non-NFA muzzle device like thee Surefire Trainer or AAC Blastout and modifying them to have 1.375-24 threads and any other forward feature necessary. I am not aware of any such muzzle device for the KAC stuff, so it would be a scratch built adapter, and may not be feasible. I can't say positively without knowing features and tolerances, though.
The Surefire mounts we can do from Trainers. The older all-steel ones are preferable, easier to convert and thus more cost effective. The newer aluminum bodied ones are doable but more involved. It can be done with Wardens, but I don't at this time. They require a forward piece be added that includes critical internal dimensions, and typically would end up more expensive all-in, longer and heavier than a Trainer conversion. |

For sure they are heavy and a bit dated but now I can run them again. The HALO mount always came loose and the 18T mount was just atrocious...

Even at that, we still have to hit a few of them with the wire wheel for them to go smoothly, but I'm not willing to go any looser on the threads. |
