That is interesting, and I will file that away for future reference...Thank you!

OR... you could...use a small triangular Swiss needle file (or fine tooth metal saw) to make each "step"...

I guess you mean the groove/serration, not step, since cutting a squared step is a lot easier, but no, I'm not doing filing...
What I'm thinking now is to use a 4" long threaded M16 barrel chunk to hold the base/ramp upright in my vise and mill the grooves with the 60º keyway cutter...It'll be sharp points top & bottom, but I should be able to level & square the base/ramp and cut it...
Something like this, but with vise turned 90º and the ramp angled 180º straight up (after it is cut)...Possibly...
Or, if the front 'ramp' (ahead of the sight base w/dovetail) is wide enough, and the rear [serrated] ramp is short & low enough, possibly I can mill 'steps' like the P08...It's odd that the barrel/sight blueprint doesn't show measurements for the ramp serrations...
