Nikon Buckmaster Scope Turrets and Rifles

I have a 6-18x40 Buckmaster on one of my rifles that has the tall target turrets on it. I like the shorter turrets like on my 4.5-14 Buckmaster. The taller turrets stick up enough that I think the proportion on my rifle looks "off". I want to make the rifle look more "streamlined".

Has anyone here switched theirs from the tall to shorter? I called Nikon and they told me that they do not sell just the turrets, unless you get custom turrets which cost $100.

Any place to buy the turrets from that you all know of? Or will they easily switch out with the shorter ones? If so, I might need to find someone to do some swapping with.

If you take the bolt out that olds on the turret, you will find that it is tall, but hollow. The teeth are on the bottom and it resembles a thimble. You could take a half inch or more out the the middle and everything would still work the same. That would not affect the mechanics any.

All is need is a shorter turret, bolt and cap.

I have bought 3 or 4 6-18's over the last two years and none of them came with an extra set of turrets.
