I got a look at it at a gun show in Spokane this weekend, the guys from Olympic were there. Its a type 1 receiver, investment cast and finished machined, I believe metric. I'm not sure if they are shipping yet, the one they had was sn 0001, their show gun. This receiver looked like it had taken some knocks as a proto and going from show to show. Generally looked to be well made, nicer finish than the Imbels they happened to have.
The rifle they had assembled as a show one (not for sale) indicated $750 as their "Grade I". It was a STG-58, new barrel, stock, grip. Handguard was new, or close to it. Heck of a lot nicer gun than the $500-550 parts guns I saw. They said their gunsmith had build a sub-MOA one up, but he wasn't sure what he had done with it.
Hope this helps.
