How do we duplicate the round headed rivets on our Valmets?

Thank you for your response. I should have been more clear.

The three rear trunion to receiver rivets, as found on the stamped M76 and M78 rifles. Plan is to put a M76 tube folder on a M78 receiver.

For the work, I'm going back to a shop close to home I have used before with a very good reputation. The owner of the shop said he could do it so I am going to let him.

It might be that I am not understanding your question, but in working with other builds, I started with a round head rivet, drove it through the receiver & trunion, and then laid the assembly down on a small 3-inch square piece of steel with a rounded cavity that the head fit into.

Then I would use a ball-peen hammer to pound & simultaneously round the other end of the rivet.

Clearly, there are pneumatic rivet presses that accomplish this process in a swift and clean and neat manner, but I didn't have access to such presses. I suspect that there are more than a few gunsmiths that have them though.
