Changing barrels (KWA, SRC)

[J-Man19]

I'm looking to swap some inner barrels around between my 2 guns and need some info in regards to whether it's possible to do.

KWA M4-S
-Madbull tightbore

SRC M4 SD
-stock barrel, cqb length.

What I want to do is take the tightbore our of my KWA and put it into my SRC.
Then put an M14 barrel into my KWA.

G&G M14 (parts gun)
-stock barrel

isn't an m14 barrel and hopup different from regular AEG's?

All AEG inner barrels are the same. Just different lengths.

Well actually M14 barrels can be different but that's about it (don't know about G&G M14).
