M4 Carbine Receiver realistic? Advices welcome!

[orb]

Hello guys! I currently in progress of getting a Custom Bomber GBB.
It should be a classic M4 Carbine. So I'm really meaning M4! not M4A1!
That means it must come with proper BURST markings and must also shoot BURST too!

I want to get this lower receiver:

and I want to put a flattop on it. This would be an R979. Any inputs if this setup is realistic?

Here the picture of the so far Receiver:
Prime CNC Upper/Bomber CNC Lower



The color differences between the upper and lower is correct.
I already have a KAC RIS, Colt Stock & Colt Carry Handle.

Any inputs welcome!

Regards

Dude I've always killed for one of those. For an AEG however.

To complete it you might need a MOSFET...

MOSFET for a GBB? Hmm... I think not.

Wait right... it's a GBBR...

Goddamn I'm stupid.

OK here's the so far progress

Damn. Would look semi RS if it didn't have the tape or w/e at the pin above the pistol grip.

Why wouldn't it? That's there to keep the buffer Retainer detent retainer Spring in place, it's only found on RS...
