Today, a very good friend of mine gave me a rifle for free. I believe it to be a Sun Project. On the side of the rifle barrel, it has Remington 700, and Sun Pro Japan on it, on the other side, it has a serial number. A friend of my friends bought it years ago, and when it got to customs, they tore it to pieces. It has never been fired. He found it in a box in his garage, and passed it to me for free. I believe its the TGC version, because of the gas bolt? Finding info for this gun is proven difficult, anyone know what kind of upgrades it would take? Or where I can get replacement parts?
