WTB FDE Surefire Warden

[Bchico14]

Looking for a specific generation of the surefire Warden. It must be FDE and it CANNOT have the circle engraving next to the latch. See image below for example of circle engraving.

May I ask the significance of the circle?

May I ask the significance of the circle?

A little background first, I found a 556RC for my URGI, but it is black. I need FDE, so instead of anodizing the collar I want to try getting warden collar first. So now, what’s the deal with the circle? The current ones with the circle measure slightly taller than the collars for the RC/RC2, I believe the older ones without the circle are dimensionally the same as the RC/RC2 collars.
