Spartacus, I bought one of their 10.5 5.56 barrels for a pistol build, and it was finished very nicely...nitride. Looked good, shot very well, and was reasonably priced. Don't know about their whole rifles or other components. I did some rudimentary research on them...hardly anything that qualifies as an FBI background check. They're allegedly a family owned business that started out some years ago as a machine shop operation. Quite a few sources seem to verify this, but who knows. Supposedly they have the machinery and knowledge to make most of their components...even barrels. They have pictures of the alleged machining facilities on their site so it must be true.
They seem to be big on side chargers also.
