I dunno about the gun ownership. I saw one documentary, a veteran if the Yugo Wars was interviewed, and he implied many veterans like him kept their guns, or tucked away some. Especially Chetniks. I've no idea about the laws but I imagine foreigners can't have guns just like that.
Also not sure if foreigners can buy lands. When we joined the EU westerners could by a house or a flat, but not land for a while. And outside the EU it's all different.
So check local laws with scrutiny.
If you get western wage (even if it's just minimum wage) and remote work is possible, you could live very comfortably in Eastern Europe, even in EU countries. I dunno if it's possible to get neetbux while living abroad, but that would be still fine.
