I assume you are talking about that loooong thread over there bashing His post regarding his hand finished receiver. He never got a fair shake there.
While I'm not crazy about some of his safety procedures, He was a victim of mob mentality. The first person to respond to his post bashed him and the others all piled on. Even the few posters who were trying to give him a chance were ridiculed by the mob.
I doubt that most of them have ever actually BUILT anything. Screwing a barrel into a finished receiver and popping in a locking shoulder is NOT building, it's assembling. FALs are incredibly easy to assemble, nothing like bending a flat (or finishing bent blank) and actually building an AK.
