Need a favor. Is there a pic of inside stock M3 head?

[KDOG3]

Is there a pic of the inside of the stock M3 head? (new style) I'm hoping its flat and not a raised tower....

surefire? here's the one i have:
Picture 1
Picture 2
Picture 3

but there at least 1 more brand that also uses the M3 to refer to a flashlight.
