Can g&g top tech m4s take after market receivers?
 

found a nice vltor receiver that can make a nice spin to my g&g op tech mk18 build, anyone know if it might fit?

can nobody answer ?

Nobody already did hehe

No!!

I did it with the broken gearbox from the M4 toptech of a team mate.
Standard V2 gearbox doesn't fit into the toptech receiver (Hole are 5 to 10mm shifter).
So badly, he will have to buy an other G&G toptech gearbox to fit into the receiver.
