A complete barrel with sights and forend for a BLR Takedown is $467.50.
Obviously, you have to stay with calibers which will fit your bolt head, like .243, 7mm-08, .260 Rem, .308 and .358.
You also have to stay with long action or short action.
That is $30 less than I paid for a used BLR in 358 in Oct.
