uzi stock interchangeable

[shogun45]

i have this question about the uzi stock
in germany
there are two uzis

mp2 wooden stock
mp2 a1 metal stock

now i want to know why they make two different names just because the stock?
is a wooden uzi stock not interchangeable with a metal folding one on any uzi and the reverse?

For what it is worth, the Wikipedia article on the Uzi notes:

Of the two stocks employed by the IDF, the wooden stock was the simpler and more robust of the two. The wooden stock is quick-detachable through the use of a release mechanism on the bottom side. Some commercial variants of the Uzi lacked the quick release mechanism and have the stock bolted in place. The second, and by far most popular stock on the Uzi was a unique folding stock which folds under the gun. It is robust but complex and was replaced by a side folding stock on the more compact models. Neither of the folding stocks can be quickly or easily removed from the weapon.

US commercial Uzis with wooden stocks or folding stocks often have the stock bolted in place rather than detachable to avoid violating the federal minimum of 26" overall. (On folding stock, length is measured with the stock in firing position.)

I believe the standard stocks (wood and folder) are interchangeable at the armorer level, but not at the field user level. That is judging from the photos and schematic in 1966 Small Arms of the World.

If you can tighten a nut you can switch and Uzi stock between wood and a metal folder. Nothing hard about it.
