Do you have any advice? Thanks!

Hi, I can't comment on the AGM MG42, but for this S&T one:
You remove the c-clip and the pin behind the pistol grip and you should be able to move the whole lower gearbox backward and down/out. Tappet plate tension keeps it from falling. Removing the main spring helps to remove tension on the gears as well too. It takes a little bit of strength.
If you look at my first pic, you'll notice the two lips, one at the front, and one at the back. These lips keep the halves together when it's in the forward position.
