I put a Kurz adaptor on my K to shorten it up even more. It seems to fit with the YHM standard length flash hiders (and the shorter ones). Are there any adverse effects of running the FH deeper into the can with the Kurz adaptor? I was wondering if it would accelerate wear or not be as effective at noise reduction?
Thanks. |

In theory moving the muzzle closer to the blast baffle is going to increase wear. You can always use a brake instead of a flash hider if it concerns you.
ETA: and decreasing the internal volume of the blast baffle is going to reduce performance. I believe YHM claims something like a 2db loss in noise reduction going with the kurz kit instead of the standard mount. |

I'll probably just stick with the standard adaptor than and deal with the extra length. |

What sort of gun?

It will definitely increase sound and be harder on the blast baffle. Worth it in my opinion.

Have you thought about switching to the sRx family?

I emailed YHM. They said their Phantom is too long for the chamber of the Turbo K w/Kurz. Which is weird, as it fits with my regular length Phantoms. They also said there shouldn't be any noticeable sound difference between using the Kurz or regular adaptor. So, I'll just used the Kurz with my shorty Phantoms I have on a few firearms.

I am running the sRx flash hider and adapter on my Turbo K on a 12.5. Per YHM's drawing I only have .131" of clearance from end of fh to blast baffle. I haven't noticed anything erosion yet, but I am pretty low round count. Running the same setup with a Turbo T2 on a 10.3. That has an even lower round count though.

The Turbo K calls out for the Kurz mount IMHO. It’s so compact to begin with and not really a can designed for chasing decibels but rather taking the edge off. Just go with a mini-QD brake or FH and call it a day. You’d have to shoot so much through it to notice a meaningful wear difference you could buy several cans based on ammo spend before worrying about it.

View Quote So just so I'm clear, the longer flash hider physically fits inside the can with the Kurz adapter, just YHM doesn't recommend it? |

I’m new to a YHM TK as well and went plan B for my TK. That phantom ratchet system is just too heavy.

View Quote Dimensionally, they say it doesn’t fit. But mine do? Unless somehow I bent in the innards of the can when I installed it? Doesn’t seem to be the case though. And I kind of measured the depth & length of the FH prior to installation. Email received: Hello, Thank you for your email. The TK has a blast chamber depth of 1.877”. Using a KURZ and a 4302 series Flash Hider will give you a depth of 1.910” which is a no go. With the KURZ and the 4302 Muzzle Break will give you a depth of 1.710”, good to go.

I read that the Kurtz adapter will decrease suppression by 2 dB over the standard phantom and collar. It makes me wonder if using a direct thread configuration is better or worse than the phantom and collar setup.
Anyone know? |

View Quote I’ve used mine DT on a 14”, Plan A on 11.5”-14.5”, and Gate-Lok on a 12.5”, and with Sordins on, it sounds about the same when accounting for barrel length. Very unscientific. I’d just use it with whatever mount fits your needs. Mine’ll go back to Plan A when my M4SD-L gets out of purgatory, and parked back on a 12.5”. |

You guys running the Kurz should consider going to the sRx system. Shorter, lighter, and lower profile overall. It’s 10/10.

The Srx has no secondary lock View Quote The ratcheting system is incredibly heavy, very bulky - and 100% unnecessary if the taper is made correctly. The sRx must have a different angle or something, because it hasn’t come loose on me ever. Only been a couple range trips, but zero issues. Hand tight and it stays put, yet backs right off with no problem when you need it to. The problems with the ratcheting system have been pretty well documented on this forum and several others. YHM should consider doing away with the ratcheting system IMO. Or at a minimum stop including it with their suppressors. It’s just inferior in every way to their sRx system. The sRx is shorter than Kurz, lighter than Kurz, and aesthetically looks way better than the Kurz. Phantom (IMO) is completely ridiculous and it kind of blows my mind that anyone actually uses it between how much length it adds and how heavy it is. |

I have original style Turbo K (serial #18) that's used a Plan B on it since I got it in the beginning and it's been running running full auto and it's been rock solid. Never come loose and wear has not been a problem. Honestly, I only use a mount system at all just to put a sacrificial brake in there... because I use the silencer dedicated to a machinegun, I don't really care about the mount otherwise. In fact, the gun is tuned so it won't even cycle without the silencer. If I were doing it all over again with modern products today, I'd use an AAC direct-thread brake; gives the simplicity and compactness of DT with a built in brake baffle for HUB suppressors: https://cdn11.bigcommerce.com/s-50c7cl/images/stencil/608x608/products/5913/28387/154371__26242.1681248583.jpg?c=2 View Quote I love the new AAC direct thread adapter. It does a great job at keeping compact cans, compact and light. I love the Kurz mounts too, especially since I could just cut off all my old style YHM brakes to use it on compact cans. However, the Kurz and brake does add about 2.5-3 ounces over the weight of the AAC DTA. AAC DTA top YHM Kurz middle YHM Phantom bottom. |

The legacy YHM mounting system has a bunch of threads that a lot of others don't carry. They have them for the M1A and M14x1LH for example that others don't offer. It's too bad they discontinued the 9/16x24LH for the FAL, had to use a Rugged mount for that.
They offer 2 choices for the SRX system, 1/2x28 and 5/8x24. Yes those are the most common, but anyone with a decent collection will find that severely lacking. |

Causing the taper to unlock after a few shots. In my experience it is about 1 in 5 mounts have this issue. You can modify the collar by disassembling it and lightly filing the inside of it, allowing another degree of rotation. I have two that had the issue that I've successfully modified. |

Seems like a lot of work for me to take all my Kurz mounts off to swap to SrX. Plus the cost. I have kurz on like 6 rifles for two suppressors. Thats $720 msrp. I’d rather another can or ammo.

I had to chop one baffle off my Phantom brake to fit the Kurz adapter with my Turbo K and Turbo 3.
Overall I'm happy with the Kurz system as it was by far the cheapest option to reduce the overall length in my case. |

Generally speaking I’d expect something to break or go wrong with the phantom or Kurz mount just due to the fact that it’s got a lot of extra mechanical parts to it that the sRx doesn’t have or need. |
