I have the same problem.. did you find a fix for this ?

Same problem here

@@General_Troddel no not yet, I bought all new internals, spring, barrel, hopper, and a steel cylinder head. All parts inside and have had no change or improvement. Someone had said sticking a piece of foam on the back of the magazine so as to put pressure on the hopper and to keep the magazine from rattling around. I haven’t tried that yet but will give it a go
