Does anyone know where a Tungsten Accubrake could be ordered?

Looking to pick one up quicker than the 60 day lead time from the factory.           
It is for a 24" #2 contour barrel. 

It will be fitted to my Vanguard Weathergaurd Tungsten 30-06.
I use the rifle for long range shooting and would love to take advantage of the pre-threaded barrel.
