First he has done a lot more conversions then most of us. He also said he was putting on a bead front site that is on most US shotguns. Maybe the person that is having this done is what he wants. I know he is doing a screw build on this one that I would not do. I know all the arguments for and against screws, but I would not do a screw build, especially on a Sagia. He also said there are many ways to do the conversion and this is his. He does a very good job at showing how its done.
