It's attached with two screws, although you may also need to slide a pin out, I'll take a look later. Did they explicitly say that that was the final product? I don't recall. Most people assumed it was a test shot, I know I did. Who would have thought the final sample would have been done 7 months ago? Actually, the cap may not be a bad idea, it would have to be pretty thin, maybe out of silicone or something, but I think it could work. I'm still really annoyed with Hasbro's response. I think i'm going to start buying a lot more 3rd party products now out of spite.
