Thinkng about getting into the NFA game before that door is closed, I’m currently trying to research what can to go with… Only thing holding me back from the AAC cans is I keep reading about the “ping” on the AAC flash hiders being magnified by ear pro… Considering I’ll still be shooting mostly unsuppressed, that would be bothersome to say the least.
So, I’m just curious to hear feedback from those who are running the AAC flash hider with ear pro?
The only people who care about this are the same people who put grease on their action spring to eliminate the “sproing” twang.
It’s never bothered me. If you don’t want the ping, just run the brake, the brakeout or better yet the newly announced brakeout2
just go shooting with a bunch of garand guys. there will be so much “pinging” goin on you wont know whos pinging who !

I feel this is a bit “overhyped.” Is it noticeable, sure. But it really isn’t THAT bad
Not all AAC FHs ping the same. I have several- they all ping, but one of them is all but silent, and one is so loud that I always get comments about how annoying it is at the range and on my videos. I already have a Brakeout for that rifle, but I just haven’t gotten around to swapping it out.
If you are indeed worried about it, just go with the Brake or Brakeout from the start. You won’t know how much your FH will ping until you put it on your rifle and shoot.
Somewhere I read an interesting article on trimming the 3 prongs to slightly different lengths eliminating the tuning fork ping.
I haven’t tried it as only one of my 2 51T Miter mounts has pinged to me. I also try to shoot suppressed 99% of the time to save my remaining hearing. YMMV
IG said it best, if you’re hot and bothered about the ping then you need to look a bit harder at what you want out of your rifle.
It’s not really the ping that bothers me, I was just inquiring about people who have first hand experience with the blackout & wearing ear pro. In my cursory research on the topic I read ear pro can amplify the ring and it can be annoying. I’ll take the fact that AAC cans are as popular as they are as a clue the ping isn’t anything to worry about.
You might wanna hold out for these new OSS cans. Word is that they are pretty good.
Truth be told I really want to get a Saker 556 & 762 but I’d hate to mix match cans… I’d rather go with 1 line and I know there will be droves looking for the Saker 762 and we have the 41p clock ticking so if I try holding out for that I might end up NOT having a .30 cal can at all.
I would be more concerned about the “positive lockup” of their 51T mount or might I say their lack of solid lockup.
My SDN-6 constantly skips a few teeth & has to be retightened after every mag. I wouldn’t buy it again based on the mount.

I noticed it the first time I shot my AR with it installed. Never noticed it since. Until seeing this thread, I had completely forgotten about it.
I’d read a little on that topic but I thought it was a relatively minor problem?
The Smith Enterprise’s Vortex does the same “ping”. I don’t mind it a bit. Love it when my rifle sings.
I noticed a “ping” yrs ago when using active hearing protection, or when the bare muzzle banged into something. The aac cans were the new at that time. In the last couple yrs I have not noticed any AAC “pinging”. Perhaps they have changed the design slightly or my hearing is shot…
They still definitely ping.
Probably hearing loss. 
What? Where?
All mine ping, in both 5.56 and 7.62. Brakeout2 was announced at shot, search for some posts by rsilvers.
ETA: I also don’t find it annoying or offensively loud, I could care less if it pings, whistles or sings karaoke.
Oh that thing looks like a winner! Almost as good flash suppression as the blackout but with better recoil management than the breakout1? Glad I learned about it from this thread!
So the tiny ping is bothersome, but the boom of the rifle or the crack of the bullet isn’t an issue? I ran mine in a class, about 1000 rds, amplified ear pro and yes, I noticed it, but you get used to it and press on. If you live near an airport, you get used to the planes overhead, same concept.
