Direct drive,

I'm really new to this AR world so I won't' try and BS. The way they explained it to me is the mag upper will hold a heavier bolt carrier group or Vault as you call it but will still use the 15 lower. It's intended for the wssm builds. The testing is done and it is working great. They also have a new recoil reduction system coming to market that I'm thinking about adding to the package.

If it don't allow me to push much extra for the .458 then I'll be building a wssm on it. Just not sure what caliber yet.
