I’ve got a
Cybergun GSG 522 RIS, which is an incestuous spawn of an H&K MP5 and an H&K UMP. This may be a n00b question, but would UMP magazines fit in a standard MP5 AEG?
I’m mainly asking for aesthetics purposes; sometimes in my film projects I need to mod one gun into 5 different guns (e.g. swap sights, lights, etc).
