Quick question for the experts here. This is my first experience with the Nova, and when we opened the box, we found the ejector spring and ejector pin were free in the box. I can put them together and the gun ejects shells fine, but the parts list calls for another pin (labelled part #047N). There's no sign of this in the box, and a quick search of Brownell's website doesn't show it. Is this a real part or a phantom part? Thanks for the help.
