I used to own a Mini-14 that I traded off for something or another. It was a fun rifle and a very handy truck gun. I have been casually looking for another one and am getting sticker shock. From what I recall you used to be able to find a clean used rifle for $425ish and now I can't find anything under $550 for a rifle showing a lot of wear. I am not in a rush to buy one but is this typical?
