My front sight post it backed out until it's loose just to achieve a 6 O'clock hold. The base is "f" marked so I'm not sure what's going on. The rear sight is a mbus which was used on another rifle without issue.  I bought the barrel with fsb from Aero a few weeks ago. Only thing I can think of is that even though it's marked it may not be a "f" height fsb.  Any other ideas?




EDIT: Found my calipers, nothing like an "F" marked fsb that measures 1.94"

It's ok, I found a .040 taller fsp from Whindham for $5 shipped so it's all good.

I am kind of ticked at Aero about this. I guess they don't understand wtf F marked is supposed to mean
