What I've gotten from them so far by email is:
1) the alloy used in the manufacture, from appearances I would suspect a 70 series alloy, possibly 7076
2) Weight is approx. 3 pounds
3) The Op- rod guide is replaced by a more substantial block, but you
can use the existing block should you choose to.
4) Cost delivered will be $922.20 to your door. (this would be to SW Ont).
I've sent another email about what is included (buttstock, fwd handgrip, etc). Probably have to wait til Tuesday for a reply. From all outward and inward (oprod block) appearances, it is very similar to the SAGE. In discussion with SAGE's sales rep, it would cost me about the same thing to pick up at the factory in Michigan, for their version, after $ conversion and tax.
