Yes every dawson style front style have the counter bore, as i heat the fiber i pull on it hard enough to sink in.
Then by personnal choice i black it out with a sharpie, and on certain hard to see indoor ranges i clean the black off.
I just took a bit of black out off right now for a pic, sometimes pictures will not do justice but the 1.0mm is much more delicate than 1.5mm, and if you track the front sight correct during recoil there is not need for a red blob to help hunt for it.
You will notice during an ipsc match, when some match director decides he want a 5" plate at 20M, a more delicate fiber will help.
The b'ack bottom right corner is some sharpie that did not go out.
