M4's w/ Crane Stocks rear wired?
 

Are M4's with crane stocks typically wired to the back? I want a good m4 with RIS rails and i want to be able to use them and not have to encumber it with a bulky looking PEQ box. If anyone could suggest a good gun as well, that would be much appreciated.

That's the purpose of the crane stock, for it to be a battery compartment. So yes, they are rear wired.

Well, not quite the purpose of a crane stock but, yeah, battery compartment. If you want to be able to put pretty much ANY battery in your AEG, get a full stock. ;)

Welcome to airsoft

If you want a retractable stock m4 with a rear-wired config, crane-stock would be good and a lipoly battery in a buffer tube.
I would prefer Lipo in a buffer tube as the wires would not be stressed from moving if it is on the crane stock.
