I called around a bit and another shop a bit further away has a used side-folder for $660. It comes with a 5 round magazine. I'm going to go check it out before work tomorrow. I don't know whether it's the newer heavy barrel or an older thin barrel. Does anyone know by serial number when the change was made? How obvious will it be if the side-folder is the thinner barrel, especially if I don't have a heavy barrel to compare?
I have one of the older pre-ban Mini-14 Ranch Rifles. I hate the fact it is not accurate. I love how fun it is to shoot and the fact my wife, who was an employee of Ruger at the time, surprised me one Christmas with it. (Surprised in a good way.)
Since she only paid $140 for it 20 years ago, I can't say if your price is good or not. I wish gun broker had a historical search feature like eBay.
