Receiver for Madbull Outer Barrel

[TheYellowDart]

I acquired a Madbull outer barrel, but it won't fit my old Classic Army M15A2 metal body, nor my newer Matrix M4 metal body. There's a bit too much material on the the part of the barrel that inserts into the receiver.

Would someone be able to tell me what brands of metal bodies work well with Madbull outer barrels? G&P, VFC, etc? I assume Madbull would work.

My madbull fits king arms receivers no issues.

You can also take off some of that excess material on the outside with a file to get it to fit - its the inner portion that matters the most.

Just file down the metal receiver cause madbull stuff are tough. Go slow, it's better to fit snug than to wobble.
