That's fine if it's not allowed, I'll just select something else. As far as being too new for the campaign though, the main campaign is set in 2000 unless I am mistaken. FN's design process on the Five-seveN was from 1993 to 1998 and in production in 1998. Adopted into service since 2000, so it could fit. Jace has final say of course and if he said no go on it then I don't have a problem.
