I have wired a gun custom for a guy with 16awg wire and allowing the use of a battery Front OR Back
This was certainly a job and a half to do as any of you experianced guys will wonder how the hell I managed to fit all the wires inside the mechbox. Well, you can check out my work log here:

the metal body had to be modified to allow the wires to be routed on teh outside of the mechbox as well feed wires inside the buffer tube into the crane stock. Well I'll let the pics tell teh story, just don't ask how long it took me to do up.
