I bought up a several guns for a package price. One was a ruger mini14. Looks to be in good shape. I don't think its ever been fired. It looks exactly like the one on this link

It has wood overtop the barrel where most I see are not built like that. Was they all made like this years ago and now have the metal shoud in the recent years?
