RE: KRB7 Rolling block
UC: No that does not work. The hammer spur and firing pin actuator are one piece so that when you put pressure on the hammer spur it automatically rotates the firing pin actuator up out of position. If you decock, the firing pin actuator will be up out of position just due to the pressure on the hammer spur when you let it down. There are a couple of ways to lock out the rotation but the problem with that is if you did it when the hammer was let down it would press on the firing pin as there is no half cock in the action. I am not crazy about the design of the automatic safety but it is not a big problem. The good part is that it can be carried cocked and only become capable of firing when the cross bolt safety and hammer spur automatic safety is released. If carried uncocked with the automaticfiring pinactuator off the pin then the cross bolt safety becomes rather unnecessary and the rifle can be cocked and the firing pin actuator rotated with little effort and no noise if you pull the trigger to set the sear (this is somewhat safer than normal single action rifles as if the hammer falls it cannot set the charge off as the firing pin actuator is not in position until you rotate it up and you cannot do that unless the sear is engaged and the hammer is in full back position). I hope this is less confusing to understand than it was to try to explain.
