Rob--It has elements of both Ruger and Farquarson.
the pivot on bottom is outside like Farquarson.Kent says
the hammer and firing pin, etc is more like Ruger.
This action being done and working, it might be a little easier to program machines to make it.Glad we are getting closer on the 12GA FH.I may have action ready to do testing
in a month or so.Ed.
