I've been talking to Joe at Kings Armory and he has followers and 6-shot holders for the MP-A's. He'll also cut the shotshell tube to install a Tacstar Supernova extended mag tube. They can also adapt their brakes for use on the Hatsan MP's. He's checking on different stock as well sense the length of pull on mine is a bit long. Bastard, call Joe. I bet he can help you with your elevation screw problem.
