Send it to George at GAP and they will CNC it for a perfect fit. I "think" they charge $120-140 or thereabouts for the mod.
I've seen a couple here in the bolt rifles section where the owners took pics of the stocks afterward. They were perfect
and looked pretty damn cool cut out for that action.
GAP will do it, or send it directly to Badger (maybe they give it to GAP) to mill. Honestly, any decent smith should be able to mill it out to the m2008 spec without too much difficulty.
