Like I said....., I could be wrong and it looks like I was. But look at it in a different way now. Through all the words and discussion BBB has come up with the goods and because of me and him you all know the answer and will now be sorting out your glued-up sights.
To me it is a totally unsatisfactory way of doing things. It's like leaving out the clicker spring in a Bren backsight or the No32 sight. Just waiting for something to rub against the knob and it's out of zero. Totally alien to my way of thinking confirmed in thread 3 when it appears that they were listening to me and did improve the system later!
Back to the drawing board
