friction/drift, no adjustable screw............
Well, mine came with a set screw on both front and rear... Maybe they're still finalizing details?
I was going to post a pic, but it was HUGE...
FWIW, the front sight measures .360", and the rear is .380" but I haven't fired it so I have no idea if POA = POI.
Another kind of strange thing is that they have white dots on the front that correspond to where the tritium is on the rear. Odd...
