Probably the most unique and successful action is that of the Omega but even that rifle has roots in the past. Most any other design you see by any manufacturer is close in concept to something that came before. I don't think Knight is more guilty of that practice than anyone else, bp or otherwise.
But Knight does have a design team that seems (IMHO) to have the major objective of creating coyotee-ugly implementations.
Check this out for some not-so-ugly deals on Knight's better rifles:
