I think McMillan and their lead times are the best thing that ever could have happened to Manners Stocks.
I know I wanted a McMillan for a build last year and my timeline didn't allow for a 9month wait (my buddy had one going at the same time and did in fact wait 9 months for a McMillan) so I went with a Manners in stock at Stockys. I eventually found a McMillan on GB that I picked up just to have for the next build, but I never would have considered Manners if McMillan had been available.
Manners has stepped up/stepped in and become a go-to product on rifle projects because they can manage to make their products available, and it appears a number of shooters now appreciate the quality of the Manners who never would have owned one had McMillan been able to service the demand.
