School me on: lightweight stock with ARCA rail fore-end, MTU or larger profile barrel channel

[Mr. Wolf]

I want to build a lightweight NRL Hunter type rifle on a lightweight stock, ARAC rail, and an adjustable cheek riser.
Looking for something like the Manners LRH-SC but with a larger channel than can accept MTU profile barrel.

Other considerations:
Manners PRS1/PRS2 - prefer slightly longer fore-end, prefer lighter weight (~3 lbs)
MDT CRBN - uncertain if Sendero contour will fit MTU profile barrel, out of stock
Grayboe Phoenix 2 - not sure what the shell is made of, added accessories add weight and price compared to LRH-SC
Foundations Ezekiel - unknown max barrel diameter, added cost, 3-4 months wait time

Not looking for a chassis. What sayeth the Hide?

Altus has some Ezekiel stocks available.

Foundation all the way.

Pure precision stocks are pretty great. I've got 3 of them
