    As I’m now working on the sidewheel of my Big Nikko Mk2 I thought I may look at trying to increase the gaps on the sidewheel for ranges over 40 yards.....

    I’m told there is a ring on the front lens that can be adjusted...... any tips?

    Cheers

    What’s your minimum distance you can focus to ?

    So when your wheel bottoms out your at 10 yds or does 10 come in and then you have a little play ?

    From memory the gaps will open slightly if you reduce your bottom range to 11 yds.
    You need to be to make sure your gaps are progressive.
    You may get 1” between 25yds-30yds then 1/2” between 30-35yds then back to an inch for the next gap.
    They should just get progressively smaller .
    You will need to make a tool to fit the slots in the ring and I would advice cutting a card circle to fit the objective lens whilst you are turning the locking ring.
    Pretty sure you will need to take the outer end off the scope before you can adjust the focus ring .
    Mark your starting point with a marker so you can put it back after you’ve had a play .

    If it’s just bigger gaps your after , it’s probably best to just fit a sharks fin .
    Think it takes you up to the equivalent of a 7 1/2” wheel.

    Or fit a magnifying lens to make to gap appear larger.
    The scope will become less snappy and you will lose the 10 yard setting if you make the 50 to 55 yards marks too far apart.

    If it's a good rangefinder now, there's not much to be gained and much to be lost by messing with it. I have quite a small wheel on my Mk.2 Nikko and about a pellet width gap from 50-55, but that gap is more than enough to rangefind to the yard. You just need a precise pointer and, if your eyes are bad, a magnifier.
