Get a cz 453 American if you can find one. IMO the set trigger is worth it. If not the 453 then a 452-455 wouldn't do anything short of impress. Just so you know that on a cz the bolt throw is retardedly high and requires mounting of the scope rather high, the safety is backwards and the mag well should be immediately replaced with a aluminum DIP unit. (Stock one is a POS)
