We had a hiccup, the front sight is not tall enough, right now with 8.5mm front the gun zeros exactly at 8 yards and high 3" 25 yards.
Which is about what you expect taking into account bullet trajectory rise.
So there is no down adjustment, need to test 9.5 front this weekend, then we have to get them made. (sucks)
