Ejectors are also pretty strong. I have been getting some brass from casing strikes on the forward assist. I think there is something fishy in the ejection, but I just don't know. That is something I need to find out....
I also took some photos of the magazines. It does seem that the magwell was designed around the new H&K mag. This new magazine is very thick, for instance a lot thicker than a G3 magazine, to allow it to be made with enough structural strength from plastic.
