Do you have more specific details about the rifle and scope? On the surface, it seems like you have probably found a good deal. With that said, the NXS line has a pretty wide range of price points, depending on the features of the particular scope, and A-bolts don't tend to bring a lot of money on the used market. I've never really understood that, because I am quite fond of the examples I own, but those are my observations.
On the bright side, you're rolling up on the perfect time to sell that rifle. Deer season is right around the corner and the market will be about as hot as it's going to get.
