This is in response to the creators of wraithmaker, Alliance Armament, stating the MD-20 is cheap plastic. And that the MD-20 big and "service reliability" implies that their expensive drum needs to work properly. Do not fall for their shit! These videos are a few things clear. Watch and see what is really the most convenient, the drum weaker (and I'm not talking about price)! Be sure to watch all 3 parts and turn your volume.
