I tried the Manners route. Called and spoke with Tom. Super nice dude. Very, very helpful. Got my stock pretty quickly. But when all was said and done, I went back to McMillan. Their Remington Classics, Mountain Rifle and Remington Hunter patterns are just too much to my liking. I've not tried the EH or SL stuff from Manners.
That said...McMillan sucks with their garbage communication of wait times. Either tell the truth about being slow or manufacture in the stated time.
