Ruger M77 Markii stocks?

Hi I have a Ruger m77 Markii 270win I hate the stock on it was wondering what is available for stocks minus ordering a McMillian for it? What else is available or used to be? Would like a fiberglass/carbon stock. Did hs or bellncarlson ever make them for this rifle? I seen hogue has some available for it are they a good stiff stock?

600, my son has two MKII rifles which came with laminate stocks. He searched, but didn't find a carbon fiber stock. The laminated stocks are very strong and Boyd's has them for about $150 - $200. Perhaps another member may know of a carbon stock available. Good luck
