crane stock help

[Gills]

hay every one.
I had recently bought a crane stock and custom made a crane stock batery for the stock.
the wiring and plug goes threw the buffer tube.
my gearbox is wired to the back, but I need it to go threw the buffer tube.
My question is how do I get the wiring into the buffertube for it to connect to the battery without pinching wires.
any help is appreciated, thanks much.

You need a new stock ring with a cut out in it to fit the wires through.
