I'm not sure if u should do this. The rifling is different I
think in a 16 inch barrel compared to a 20 inch barrel. And if u
shorten it u will have to recrown it. Tbh u will prob ruin the
accuracy of the gun. I'd just go and swap it for a 16 inch model

A friend got his Cz cut from 20 to 16 re crowned and screw cut
again. Never affected accuracy one bit.

Its only centerfire rifle that suffer accuracy probs after
cutting as they have more compression.
All the compression/powder is burnt in the first 14"/16" of a
rimfire.
If the person in queation has good lathe skills and know how to
do a good crown let him work away.

The crown would be the most important issue with a barrel chop -
accuracy wise. I think its cut at 11 degrees.
