Junior Sight block riser adjustment

I have a junior that is 14 and won't stop growing. He is now approximately 5'10" with a long skinny neck. The problem is going from prone to offhand and kneeling. As he has grown offhand and kneeling head position has gotten worse (tilting down) to get into position. I used a set of riser blocks that came with the rifle that are like 15mm high. Put them on for offhand and kneeling but to high for prone. I bought riser blocks (Gamhann 849W).
I have a couple of questions:
Gun - Walther KK300 with stock rear and front sights.

1) Best way to adjust riser blocks.
2) Does he need to shoot prone, offhand and kneeling with same riser block height?

Thanks

No, he does not have to use the same height riser blocks for all positions. Use what give the best comfort and sight picture without excessive head cant.

If different heights are excessive, it may pay to get multiple sets of sights.

10.9 has riser blocks that have a wide variety of adjustment inserts.
They also have a touch of offset adjustment as well.

The only issue they you will have with different sets of blocks is making sure they are paired correctly on the rifle ... color code them or something to make sure you don't get them mixed up.
Especially important if your shooter makes the final now ... you have no time to correct for a mistake.

With the new rules and times we took a diff approach. We went with a universal moderate sight riser and just change butplate and fore end to raise and lower the gun...less is more??

Her air rifle and smallbore are nearly identical for standing yet set up completly different.

I tend to agree here. Since Feb last year, specifically in the finals, I've seen too many shooters rushing to get different risers on during the finals and mess it up ... essentially taking them out in the first elimination in the finals.

Get a good set of risers set (as "red" says moderately) and use cheekpieces, buttplates and fore-ends to move the gun around. My daughter has different fore-ends for the kneeling and standing positions ... and in the standing ones, three of them, that are set for a 55-1/2 target height (50ft) and one for Benning and another for the OTC. Much faster to swap out the buttplate & fore-end than messing with the sights.

Putting the sights on different risers might be "more perfect" for the qual stages where you have lots of time for sighters, but in the finals the time to zero sight riser changes just is not there anymore. You want the gun within a few clicks of zero in the final ... you only have time for a few sighting shots.
I'd prefer my shooters learn to shoot the guns as if they were in the final and not use different "techniques" depending on whether they are in qual or final .... Train for the final.
