I have a TM M4 with G&P metal body and I would like to upgrade my plastic handguards to metal. Does this mean i will have to rewire the battery to the stock first? Do all the metal handguards come in one piece, or are some the same format/function as the plastic ones but metal? I'd prefer to keep it as simple as possible and just get two-piece metal handguard and continue to keep my battery in there.
Is
this what i'm looking for?
Any advise is appreciated!
