Hi Timothy and welcome. There are not much internal differences at all. In short, the differences overall are more cosmetic. Cheers, stay safe and enjoy!

The Browning Maxus 2 Camo and Maxus 2 Wicked Wing are both semi-automatic shotguns, but they differ primarily in their appearance and target use.

Both models share the same underlying design and reliability.
