ISO 9 twist .510 barrel, or faster....

[ST42]

Anyone here have a lead on a 9 twist, or faster.510 barrel? I have an order in with PAC-Nor for a 9, but its looking like I may not see it in the next several months. It has already been 6 months, and I’m getting eager to get my .510 whisper finished. Any leads would be appreciated.
Thanks
