yes it was the 9ball 6.03 inner barrel, well since it's a marui the shell "should" be more resistant than the clones ones, but again, why marui is so durable... because it fires at a relatively low fps... (yes better qc and materials too but still...) and i cant really say much to you on the springs sorry... all i can say is that USUALLY the stuff that comes from 9ball is of better quality than deepfire.
