I appreciate the offer and links, I should have been more specific. I need a laminate, bell & carlson, manners, mcmillan or chasis. I have a custom 300 blkout with a heavier contour barrel and i dont think the plastic stocks would have enough meat in them to open it up.
I have a new HS Precision PSV063, Black and takes a Rem Varmint/sendero from the factory but can be opened up for bigger. Its a nice stock its I just don't have any more model sevens left. PM me if interested. I did exactly what you are doing but in 6x204. https://hsprecision.com/product/psv063/
