I own two M4 models, one from CAS and one from Mach1 - Same upper receiver, not a difference at all. Maybe the model I bought from MAch1 was older or newer or something, but in comparison externally and internally, the only difference is the lower receiver, CAS having a smoked one. Now with that said however, when I say internally, I don't mean the gearbox. I haven't cracked either open yet to compare parts but they both consistently chrono out the same with .20G and .28G bbs. Put 1 - 1.5K rounds through both, no issues yet.
