If you want you can run it how it is, but I suggest a 13/3k if your running the bottomline, just because I think it balances better, and you can still get 150-200 shots off with it.
TPC does let you get rid of screw, but also doesn't like brittle paint. Ups your efficiency also.
And to adjust velocity with a flat head, your gonna need to take the barrel off.
