If it's just a Bubba conversion, you paid too much.
Going price is about 200. If it's got a new stock and the mag has been altered, not so bad. I'f the metal hasn't been butchered, always the option of converting it back to mil spec, but that will be expensive as well. Definitely rated as the strongest military rifle action out there and used to be a common choice for magnum conversion.
