Here are some photos of the stock to which I am referring. It's actually very nice wood for a production rifle, with cut checkering and a satin synthetic finish. Inletting is very clean, but as you can see the primary recoil lug under the front receiver ring is comparatively shallow and unreinforced. Hence much of the stress from firing will be transferred to the rear of the magazine box, as well as the top tang, especially if the metal is bearing directly on the wood at that point. The recoil lug on the barrel is a useful addition, but by itself would not be sufficient. Personally, I prefer a big cross bolt through the stock under the front recoil lug for anything bigger than a .30-06 class cartridge, but even an aluminum block embedded with a bunch of epoxy bedding would be a big improvement over the factory design.
