What should I looked for to value it. Appears to be on a Remington 700P in .308. Target turrets. I think that it had either Heavy Duplex or Mil Dot reticle. Premier Reticle sticker on it. Think it had a front AO. Worst case this is a $300 scope correct? Looking at $850 otd, and figuring it is a deal if the optics are worth half. The shop is of little help as they told me over the phone that it was a VX3. Since I was fondling it Saturday, I know that much is incorrect. Trying to keep my questions simple.
