King Arms Selector Plate for M4 Series Airsoft AEG Gear Box

"Selector plates are pretty much selector plates, yes the type of metal does make a differince, but as long as you get a KA, G&P, or systema selector plate you will have no problem, but the KA (King Arms) is great its very strong plastic and the metal chip is copper coated for conductivity. Only thing is it may need a bit of moddification to fit G&G recievers, you may have to remove a centimeter or two from the back (side without the metal chip) but that is easily done with out a snag.
