Ok, I have never really been into AR's much, more into the M14 and AK styles. However, a lady my wife works with is wanting to sell a couple AR's her husband had (he passed 4 years ago). I think I might pick one or more up if she is not completely crazy with the pricing. Also, I don't really know the pre-hysteria pricing and was wondering if there are some general guidelines such as Colts - $1500 to $2000, etc. Could someone give me just a very general pricing guideline of how much different common brands would be worth pre-hysteria? I don't want to overpay and I also don't want to short-change her. I realize this is something of a big and possibly difficult question. Please flame/delete if necessary.
