Mine doesn't ping, but its on a 10.5" barrel.

I shot several different guns last week that had AAC flash hiders on them, and I used electronic ear pro.
I cannot say that an annoying ping was something that stuck with me.
They did have two different designs, with one having rounded prongs and the other having flat areas on the prongs. The one with rounded had a distinct ping when we tapped on it, sort of like a tuning fork, but nothing I noticed when shooting.
The AAC guys were only there for the demo shoot, and one day for the course I took, so didn't have time to ask too many detailed questions on the suppressors and flash hiders. They do a great job of reducing report, as well as reducing felt recoil.
It's not about surviving, it's about winning!
The ping is barrel specific in my experience. I've moved a mount from one gun to another and went from no ping to some ping.
A badly pinging barrel/mount combo can be annoying. Moderate pinging never bothered me though.

Thanks, moderate pinging wouldn't bother me either. My worry was only the combo of significant pinging being greatly amplified by ear pro to the point I'd be looking to use some old school ear muffs... I think my only problem is every rifle I own has a lightweight/pencil barrel, which I'm guessing may be the worst profile for the ping.
Finally found where I saw a comparison pic in 308 at least.

This..
Funny thing never noticed it during the class, to busy trying to listen to the instructor, hit my target and ignore all the firearms going off next to me..

That's what I would consider "mild."
Here's what my worst one sounds like, and the sound in this video is exactly what you hear through electronic ear pro- a pleasant sounding report from the rifle, followed by a drawn out whine from the FH. None of my other AAC FHs ping as bad as this.
