I bought an Uzi from them a few weeks ago, and promptly sent it back. No German stamps or paperwork with it, just a "Certificate" of deactivation from the dealer. On the said "Certificate" it listed what had been done to deac' it (Which included having the barrel welded to the receiver, and also the trigger group "Fixed" to the receiver.). I promptly unscrewed the barrel nut and popped the barrel off, and pulled the strip pin to drop the trigger group out. Sending it back saved me a court appearance, or a lot of explaining to the Police, in my humble opinion.
