G&P upper on a king arms lower

[horto]

Guys,

Haven't been able to find an answer nor do I have a King Arms AEG for test fitment.

I have a full complete G&P mk18 upper that I'd like to mate to a King Arms Colt M4A1.

Does anyone know offhand if a G&P upper receiver is easily compatible to the King Arms lower?

Thanks in advance...

I'm actually curious about that answer too. I am also curious to know if a proper delta ring screws onto the threads of a G&P upper since their barrel ring is not a real delta ring.

Anyone?

Ok, I just tested with two of my guns and the G&P upper is too loose a fit.
However, I can't guarantee that this is the result for every version of each brand.
I used a KA VLTOR lower and a G&P Magpul upper.

this may sound like the most noob question but did the KA delta ring and the functioning bolt catch work on the G&P upper? I have a KA CASV ris and it relies on that delta ring to be mounted.

why would you even try to fit a GBBR upper on an AEG lower? thats like putting a airplane wing on the side of a car as a door.

Actually, he worded it a little ambiguously.

What he meant was that he tried fitting (my) G&P WOC Upper on (my) King Arms WA GBBR lower. They don't fit - which is probably likely similar with AEG variants. The notches (for body pins) are reversed in sizing (not sure if that is clear, but I'm not sure how I would describe it otherwise).

Most AEG variants are compatible (as long as they're the same style, like G&P, KA, etc with the front pin holding in front and the lip holding the back in)
