Maybe the plastic is hinged and reveals a hole lol *shrugs*.How would you ever connect a nunchuck to this?
But yeah it's obvious if the pics are of the item that it can't connect to a nunchuck.
Anywho the one on DX looks identical to the one on Emvee and if what The Last Spartan says is right and Emvee buy all of their stuff from DX, the guns will certainly be identical so neither connect to a nunchuck.
