The M4 platform is designed to be modular, yes. However, it is difficult to find spare upper receivers for most airsoft M4s. The G4 upper is one of the only "Sold Separately" uppers that are available. Its design is also easier to switch than many M4 receivers.

You were warned, not for voicing concerns about our items, but for flaming; not just us, but other users as well. We want debate, but there's a difference between debate, and badgering.
We're just trying to cultivate a friendly atmosphere here in our forum. There's no reason we can't be civil. :P
