You won't like this, but I think you will be lucky to get $800. Nothing wrong with the rifle, it's the economy. If it was priced right it would have sold. Nice rifle, but you have to find someone with exactly the same taste as you. Like many things, when you customize you don't get your money back. Applies to guns, cars or motorcycles. Put it back in the safe.
It's hard to get what you paid for, for really cheap rifles and customized rifles. That's why I buy good honest rifles that are easy to re-sell. Hint....
