i recently just picked up the mp5 that i won in the raffle and when i went to test it i saw it was a large type connector so i put a converter to a small type for my battery. the battery was fully charged but when i tried to fire it did not work. it only made a sound that the battery was dead and the battery and the adapter got hot..i also tried 2 other batterys and it did the same thing.
CAN SOMEONE HELP!?!?!?
