I've got a friend that ordered one of those, or one like it. Supposedly, it was 75%-80% complete. He found out pretty quick that whatever parts needed to be finished, took a lot more work than he was led to believe. IIRC, he had to drill some holes or maybe drill out some holes and something else. It took some pretty meticulous workmanship to finish the rifle, but he eventually got it done. When finished, it worked.
