The front "leg" on the scope is opposite to the rear in every way. The camming groove is toward the front as the rear one is toward the rear, hence the cam levers locking toward the centre. The scope fits very well into the bases and locks positively. It has to be withdrawn and replaced straight up and down.
Interestingly you picked up on something else I was thinking "T65" really means nothing without ".30" in front of it...
