I just got the AGM MP40 from airsoft armoury but when I put the battery in, the battery fried and leaked! I did everything the way the manual told me to. I'm also worried that this has dameged the inards of the gun and I'm hoping it's just the battery that's bust. Any ideas?
Dont worry if its new, return it & request a replacement, strange though its fuse in the grip did not blow, could be a short on the wiring before the fuse.

Thanks for the advice. Do you think I should return the whole thing or just the battery?
Yup, return it ASAP. Give them a bell to let them know its on the way before you send it though. I know the guys there quite well, you shouldn't have any problems. If you do, then drop me a PM and i'll give you a few pointers on how to make a company sit up and take notice

Thanks very much. You've given me much more info than I expected. I really appreciate it. I'll phone them tomorrow.
