RIS M4 Handguard Battery Housing
 

I am looking for a RIS system for my M4. My m4 is wired to the handgaurd, which makes it impossible to get a RIS without either getting a battery box :( or wiring it to the back,which I don't want to do.

Is their any M4 RIS Systems besides the Magpul MOE or the King Arms CASV that can house a battery?

Thanks

buy a slim lipo battery, it will fit in the RIS or in the retractable stock tube

Okay, I've personally never heard of it so I have two questions.
First, Do I need to buy some adapter for the connection?
Second, Where would I get it? (Couldn't find it on ehobbyasia)\

(The Picture is my Battery) Im unsure what kind it is

if your gun is stock you will be fine with the mini tamiya (http://www.airsoftcanada.com/showthread.php?t=26918)
