I inherited this parts gun from a builder that passed away. I am having trouble finding the parts to finish it. There are no markings or stamps. The barrel I was told is a 45 cal barrel. A friend of mine that works for the police said it was close to being automatic, and possibly built with the idea in mind. I am not familiar with what would make this rifle an automatic. My intention is not to build an automatic rifle. I am not sure where to get parts to finish it semi-auto. I have not been able to find a kit or another rifle that resembles it or would possibly share parts with it. Thank you for reading my post, any advice would be greatly appreciated. I enjoy shooting at the range, but have no gun building experience.
