My Vortex does that too. It doesn't hurt anything, so I don't worry about it.

I've got a Blackout on my M1A - the tuning fork effect is about ten times as bad on it as on the AR....

Thats what open prong flash hiders do. The reason they suppress flash so well and can take so much abuse is also because they are open prong. The solution to your problem is to find a less effective, weaker flash hider so you dont hear the noise. I suggest purchasing a Phantom.

Not all open prong flash suppressors do that (most of them do), and I've seen a closed flash suppressor make slight tuning fork sound too.
It's something you'll get used to soon enough. Just don't let anyone tell you it's the sound it makes that dissipates flash signature, or the vibration of the prongs

Le tme guess . . . . without reading the thread . . . . you can't stand the ping because it gets your mangina sandy?
 Seriously, I run these with their cans and you either get used to the ping or you buy another suppressoir, or you put a muzzle brake on the gun. The only solution is to use another flash hider that will not be as effective! I have sold a few of AAC's finest to folks and they love the supression, but then they can hear the ping and it drives them nuts! |

Less erosion on the open ended Blackouts as well. But, I do wish AAC would make the 18 tooth A1 birdcage again, just looks cool.

I used to notice the tuning fork ring when I got my first Blackout, but with a half dozen so-equipped systems now, I just don't notice it any more.....kinda like the spoing of the buffer spring.
One thing that I do definitely notice is the lack of muzzle flash when shooting in reduced light, even with NOD's. |

Put a hose clamp on the prongs to dampen the vibrations!
This pinging varies from gun to gun. My mount doesn't ping at all. (11.5" Colt Commando w/ pencil barrel profile) |

Just installed an AAC Blackout FS. It makes a really loud "tuning fork" sound any time I release the charge handle. Actually, it makes that annoying sound nearly every time I pick the damn gun up. Anybody have any success resolving the issue? My duty weapon has an AAC mount, and does it as well. Not a problem in the least. |

Mine does it to. At this point I don't even care anymore. If I don't think about it, I don't hear it. The flash suppression it gives is better then anything I seen. I shot with it last week late on a Friday night at my local private range. On my 10.5" SBR there is little to no flash. I moved it over to a M4 and there was none at all.

FYI, I don't think the "pinging" has to do anything with the open ended design. I have several AAC CLOSED ended flash suppressors and they also "ting". I have tried other open end flash suppressors that aren't hardened (even a knock off "Vortex") and they don't make that noise so I'm pretty sure it's more a function of the HARDNESS of the steel that AAC/SEI/etc. uses.

I can only try to explain why my custom made HK flash suppressor and AAC Phantom (made for them by YHM) ping. The walls on these flash suppressors are pretty thin, I believe if the material was thicker, these close ended flash suppressors would not ping as much. I'm guessing due to the thinness of the prongs, they vibrate more than the thicker walled counterparts.
AAC doesn't sell these Phantom flash suppressor mounts anymore, because they are not as durable. |

The pinging is just that... at tuning fork effect. A regular phantom produces noise because it's a relatively thin walled piece of metal hung on the end of a more densely materialed barrel. Barrel harmonics and barrel whip can make it ring. If I flick an unmounted flash hider with my finger, it'll ping. |

I strongly recommend ordering a M4-2000 silencer from AAC......that should eliminate that pinging sound!
I have the same flashider/mount on my 16" and their blackout muzzle brake on my 24"......just awaiting my M4-2000 to ship to my dealer this next week and send money off to the ATF for them to play with for several months before I can use my silencer. |

The pinging is just that... at tuning fork effect= The same mount/flash hider will ping differently on a different barrel. (assuming that all the blackouts are made the same) I got to hear another sample of the blackout last night at at shoot. It was mounted on a Noveske 16" SS barrel and it had a mild ping... barely noticeable, but it was there. Mine doesn't ping at all, and others have quite pronounced pinging. My guess is that it's more a function of individual barrel harmonics.

It might be a little less obvious, but if you're looking, you can find it. |

The M4-1000 is a very popular silencer so SIG put a compatible mount on their SWAT version 556 to appeal to agencies and individuals who use own the M4-1000. Maybe they tried to work something out with AAC, maybe not. AAC in turn says they won't warranty a can damaged while being used on one of the SIG mounts b/c they of course would like to sell you their mount. |
