The owners were indicted, AFAIK the matter was settled in their favor before it ever got to court. ATF returned the "improperly demilled" Steyr kits minus the rear receiver section so they were now "properly demilled" without that 3 inch section of tube. Around the same time ATF also seized thousands of Imbel fal kits for "improper demill" because the center section of the receiver was included. After several years they also returned those minus the offending section. That's where all the recent Imbel kits came from.
