Source for octagonal metal rod/bar?

[Maelstrom]

Tried onlinemetals.com

Looking to redo a wilco models mal gun bought a few years ago off ebay. Not a bad piece, but a little more warped in places than I would like.

Obviously the best result would be brass octagonal rod, but will take any metal if you have a source for it.

Found plenty of hexagonal:unsure
