I am in the process of building a Krag. My plan is to put a combination sight and hold down on the barrel. This mount will have 2 screwholes underneath for holding the barrel to the stock. The plan is to have a pillar embedded in the stock. This sightbase hold down combo is 2 inches long, but a simple hold down could be 3/8 long. Chasing the barrel threads down the barrel and adding a nut are my plan to pull this up against the reciever. I have a foto avalable of the finished sight base and drawing but am not sure how to attach them to reply.
