DPMS pattern 308 barrels

[Gutter]

Looking to get a 24" 308 barrel to complete a build before the end of the year. What's the general price range for 24 inch 308s? From what I've seen, most middling options are around $325 - $450. Is that what I should expect to pay or is there an even cheaper tier? The idea behind the build is to be as economical as possible as I have six others to build prior to Jan 1.
