I have one of these flash hiders on my rifle. I noticed as soon as I installed it on my rifle that there is a resounding ping like a tuning fork when there are vibrations in the rifle (closing the bolt, locking the charging handle, thumping the flash hider). I was wondering how many of you use this flash hider and if it does the same on your rigs.

Functionally it works as it's supposed, and no flash is a great thing to me (as my eyes don't handle contrast very well, muzzle flash is particularly blinding to me).

Great flash hiders I'll have to check mine for a ping.

yes they are notorious for that actually.

I believe that the 'tuning fork' effect is due to the hardening that it goes thru during manufacturing. I think the hardening helps with the integrity that it needs because of the open cage design. that would also explain why few other designs do that.

Ok, good. I've seen some of the older ones that had opened up from heat. Interesting that the case hardening would cause it to be resonant.

I dont think it's case hardened. It's fully hardened if anything. I would bet that it's close to an rc55 maybe harder.

I dislike this flash hider for this reason alone. I believe it's caused by the long unsupported fingers. If they had an enclosed circle of support at the exit point like other brands this problem would disappear. I doubt it's effectiveness would be reduced one iota if produced that way. Of course it would look similar to a Phoenix then. It's an excellent flash hider, I just find this quirk annoying.

The Vortex is designed to vibrate.
It helps to break up the flash.
