Value of Remington Model 788 99 percent new?

this is very difficult to say unless one knows the condition of the rifle, the caliber, with or without the magazine, and if there are sights on the rifle. Being "99% new", probably in a popular caliber of 223, 243, 22-250 or 308 I gustimate that the rifle is worth $275 - $450 depending upon the buyers need for the rifle
