You can be as harsh as you like, it won't annoy me as much as my scope does!
I don't want to confuse the issue too much, but....
The scope came free with my Steyr!
Mainly because the brass screw retaining the sidewheel was sheered off.
It hasn't bothered me that I could pull the wheel off at any time, but it sounds like it's time for a new scope.
I just don't want to spend a load of money on another big Nikko/expensive scope and find I'm back where I started.
So I'm glad to hear this is not a typical Big Nikko fault.
