It doesnt have be changed to the back, although alot of people do just because of the addition options and possibilities for larger battery capacity when you house a battery in the rear.
Front wiring can be maintained if you wish by converting to a lipo battery that would fit in your knew handguard, of course running a lipo is at your own risk. An alternate option to that would to conceal your battery in a faux AN/PEQ.
Please see example here:
