Why does my AR "ring" after every shot?

Not a joke on the muzzle device.
If it is three prong and they are equal length, you'll get harmonics.

I have four that do it.

Correct, joke in the dad joke part. Serious in the serious part where what I said was true.

Vortex. I'm interested.

Which Vortex do you have, A2, A3 or A4?

FWIW I have a couple Vortex A2s that ring...

Which Vortex do you have, A2, A3 or A4?

I think it's the A3. I'll take a look this evening.
