you could certainly get your money back out of it , maybe 50% more. If it shoots and is in decient condition I don't see whay you coulden't sell it for $300. Their are so much more build up goodies for the Rem 700 thats the reason that you see so many more built on them along with they are alot easier for the average part time smith to build up.
But if you sell it I would not buy a remington action to build on invest a bit more an get a custom action , for the cost of building up a remington right you can get a custom action and have most of your money back should you ever have to sell it.
But since you have the action I'd just build on it
