Nothing wrong with a solid MP5 or P90 either.
But, I do advise against the paintball mask. They disastrously distort and cloud peripheral vision, so some good googles and a well-fitting (or custom made) sykes mask might be your best bet.
Also, where the hell are you going to play CQB on this island? I'd love to know.
