I don't know nothing bout scopes... but tehre might be a hammer extension for the hammer.
As for the sabots, don't know nuthin bouth them either, but they are obviously too small and will not give you adequate accuracy. I'm a pure lead bullet shooter, so you will have to get some help from one of the sabot makers for a thicker sabot, then you should be able to get great accuracy and much better velocity than you will with undersized sabots.
