I use LaRue but haven't used the ADM mount, it looks like the same setup with a different attachment system.

As for the stock, I use SOPMOD stocks. I used to get em from LMT but now B5 systems has the govt contract and G and R tactical sells them for $95. They don't have a raised cheek piece but it angles out for a solid cheek weld and is the perfect height for me.
