Go over to the Saiga-12 forum and you can see that these type problems have been going on for a few years. Lots of back and forth, lots of excuses. I believe no one has been ripped off, and the guy is honest, just seems to have a hell of a time managing his business.
I understand the product is very good, but I went ahead and ordered my adapter from Renegade Buck, who makes his own design, smaller scale operation. I am very happy, love the fact that I can stick any milspec AR15 mag in with total reliability.
