Maxx ME Pro feeding issues in AEG (Automatic Electric Guns) Rifles & SMGs Posted December 10, 2019 · Report reply Who here is familiar with them? I just bought the ME Pro from maxx's website and I'm having feeding issues. Shoots one every other shot, This goes on for about 20 rounds. ONLY THE FIRST 20 ROUNDS have this issue. I learned if I only load 75 percent of my mag this won't happen. Air nozzle issues?? Please, any suggestions appreciated. The gun in question is an old king arms colt m4 moe magpul. 11 plus years old.
