Center feed body and barrels?

[Slapp]

Do center feed mag bodies such as those on some e-mags require different types of barrels than powerfeed type mag bodies? If so are there many aftermarket barrels available for the center feed bodies such as freak backs etc...?

Center/vert feed mags do need different barrels. And yes, many companies have barrels for centerfeed mags.
