WTB Proof Research 300 blackout 12.5" carbon barrel

[Btar21]

I am looking for a Proof Research 12.5" carbon barrel chambered in 300 black out. Prefer new but will purchase used if in good condition.

I would also consider another high end barrel in the 10" to 12.5" length, just tell me what you have.
