It is has become common to read these posts. I bought an "AMD65-UF" underfolder from them and it was rusting from the moment I opened the box, was built from left over parts from different kits and had bent rails inside the 1.6mm receiver. Sent it back and walked away.
I wonder too how they can be trusted to build a decent receiver when everything else they touch turns to shit. Sorry for the new guys who buy from this outfit, but they will learn, like I did, that even with AK's quality costs money. Buy a VEPR, Arsenal Inc. or buy a kit and have it built by a trusted smith.
