I'm a wood guy, but may have an option for your cheekpiece.
I have, and install the KMW hardware in my stocks. It's hit or miss in getting the hardware from Terry. I like the hardware, but it was not designed for ease of installation in a cutom stock. It was designed, and rightfully so, for the "situational stocks" that he designed. Terry's stuff is top shelf!
So the solution for the custom wood stock guys was to design a piece of hardware that functions like the KMW, but aligns itself with the high end custom wood stocks... And that's what we did.
If you look at the below pictures, which are all of the same stock, you can see the hardware that we designed for this purpose.
If you never saw the KMW, you would not be able to tell the differences. If you have held the KMW in your hand, then you will see that the bottom piece is designed for an easier, more custom installation. Everything else functions the same.
This hardware may be a good option for your no expenses spared built rifle.
