Comes down to it,the rifle is worth however much someone will pay for it.
And,it would not surprise me if the market would not do it justice.
That's the sad thing. I've heard it said hundreds of times you can spend 1000 dollars turning a 500 dollar rifle into a 200 dollar rifle. It makes no sense. My rifles will shoot rings around anything you can buy off a rack yet they're not worth half what I have in them.
