G'Day Fella's,

Clark, FYI, the alternative Brno ZKK curved trigger you are looking for (as pictured by Eagle27) is not a Set Trigger. It is just a conventional/standard trigger system (but for the Brno ZKK action).

My best advice, would be to speak with the owners of any old Gun Shops or Gunsmiths, that have been in business for a long time. Even current Gunshops/Gunsmiths, that may have bought the contents, of older gunshops/Gunsmiths. These people/places, may have the ZKK trigger you are looking for.

Hope that helps

Good Hunting
