It probably depends on the specifics; caliber, profile, material, fluted, etc. I've bought a few Remington take offs to turn into AR barrels, I'm thinking I paid an average of $75 or so.
I've seen them as low as $50 up to $200 depending on the barrel. I keep looking for a short Savage 308 heavy barrel but nothing has turned up yet and I don't want to pay a high price for one.
