    Hello.
    I bought second hand nikko diamond 10-50x60,mk2.
    It can focus on 7,5 meters,and maximum on 50 meters.
    The previous owner said to me that he made it like that,so i suppose it has 50 ft focus adapter.
    My question is,how i remove it so the scope return on its natural stage?
    I read that 50 foot adapter fits into the flip up on the front of the scope,but i dont see nothing there.
    Is it possible that he did something else to reduce lowest focus to 7,5 meters.?
    Thank you.

    No, I think that it's reparallaxed. This means that the front lens has been moved a little bit out so it can see sharp closer but not so far away.

    Very very carefully, it's easy to scratch the front lens if you don't have the right tools. I haven't got any personal experiences with reparallaxing, maybe it would be worth to google it thoroughly before doing anything.

    Really tricky thing to do as stated above mate.
    Best advice, send it to someone who CAN do this as messing with it runs the risk of scratches to the lense or worse.

    Very easy to do as I did it on my nikko 3yrs ago.
    Put a target out to 10yrds,unlock the locking collar on the objective lens, you can do this by screwing the sunshade on to get more leverage. Lock it in place by wrapping gaffer tape on the area where it screws onto the scope.
    Now put some more onto the other side of the scope body and put a cable tie around it,put it on in the direction so it tightens as you unscrew it,anticlockwise.
    I can't rememder which way it needs to be turned,the objective lens.You may need to shape a piece of metal to fit into the adjacent grooves on the locking collar to enable you to turn it in or out.
    Put it on full mag and focus on the ten yrd target.
    Now slowly screw the lens in or out untill in just starts to get blurred at the 10yrd target.
    If you have a close focus adapter you could parallax it to say 12yrds.You will then get slightly bigger gaps between 50-55yrds as the parallax works on a liner scale.

    scratched glass

    If you have a go at doing this ,cut a circle of card board to protect the lense when you slip.

    If possible, practice on a cheap scope that you don't mind spoiling. :eek:
