Hey Guys/Gals

I'm getting myself an UBR and I hear that they come with a larger Buffertube designed specifically for batteries. I was wondering if I would need to modify my gun in any way (apart from rear wiring, I have already done that) to get this to work. AKA dremeling out a hole to fit my cables etc.

For your reference I use a KWA M4
