I'm sure the Savage Accu-Stock works BUT I honestly DON'T see how it's any better than a full length bedding block or glass/pillar bedding. It looks to me like an answer to an unasked question. I've built a BUNCH of rifles, and don't see how their accuracy would be improved by putting pressure in 3D bedding. Maybe it's simply an precision bedding available for the working joe that don't know how to/don't want to bed his rifle, and just wants something that'll shoot out of box?
