If you go to the bitel website and find the bintel tube rings, they are like that. You unscrew the knob and push sideways to unlock.
I was thinking of getting a aluminium piece, drilling holes and since the knob uncrews off, putting the aluminium piece on and then screwing down so the guids scope os on the side.. But I think it will not hold it secure enough.
Maybee I should drill the rings at the top through the rings and mounting that way.
