Those are good options...
Yep! That's the way they work. Loosen the stop nut, screw the sight in or out one revolution at a time to change the height, and lock itdown when you get it where you want it.
OK that what it looked like to me - but I was just wondering...
Can you tell from the pic - who made these? I am wondering about other inserts for the front globe..
I can get a better pic if that would help... On the front you un-screw the back of the hood and the insert comes out...
thanks - mike
