Blackhawk Aftermarket rear sight?

[noseeum]

I'm a new member here and wondered if anyone can tell me about this rear sight on an OM BKH I bought. I am going to post a pic if I can figure it out. First time for everything, right? %2010.jpg

Is it labelled "Micro?"

if its flat across the back, it could be a Millett sight...........lot of them around.....
