Got my M3000 put together this morning. I didn't get nearly as deep on the loading port as most on this thread. I just filed it down and rounded it off enough to make loading two possible. Up to this point I'm not coordinated enough to quad load anyway. Thanks to Tom at MOA Precision for getting the magazine parts to me quickly. The barrel nut fit perfectly. Thanks to everyone else for the pictures and videos to show what needed to be done. Now just have to find time to take it to a match. Later, JC.
