if this is a folding stock DE warhawk, then it would solve the issue of the warhawk stock adapter not being TM compatible. I'd probably want this over the CM028S (providing it isn't the CM028S) for several reasons, such as better barrel, tm compatible hopup, and no lame feeding issues.
If it's the CYMA... they mention "precision metal barrel", so maybe they took the CM028 and gave it a TM compatible hopup/brass barrel. Well, one can hope, anyway.
