I have a 9.6v 600 mH mini battery from my "late" MP5. It doesn't want to fit too well in the foregrip on my M4. I believe I need to have it reconfigured to make it work. Does anybody know where and how much I could expect to pay to have that done? Or even if that's the way to go? I like the punch it has, so I don't want to give that up. Any help would be appreciated.
Hey! You can't park that animal here!
