So, I don't know who ordered that these rifles be rendered obviously inoperable via removing the bolt entirely. They were always inoperable, but someone went the extra step of saying "no, we need to make sure you couldn't have switched it out for a real one, that you could have loaded and used!".
In which case, why bother inviting the marines at all?
