I purchased this mp40 quite awhile ago but never opened it until tonight. I was cleaning an old MP40 and it wasn't spinning freely so to inspect to make sure i re-installed everything correctly i opened a brand new mp40 i purchased for another build i'm getting ready to start to look at the assembly of the wetside. Upon inspection i noticed this crack on the magnet. Box has never been dropped, no damage anywhere.
What should i do?
