Are Smgs Just M4 With Smg Shell?

[XukeLho]

Hi guys, first of all let me say that I am farly new to airsoft, having litle over 1 year of experience.

Having that said, you guessed it by the title, are (some or all) SMGs just M4 with SMG shell?

I was browsing some guns online, checking out some pictures and found this gun: https://www.taiwangun.com/en/electric-3/m89a-ee?from=listing&campaign-id=19 in there I found an exploded view of the gun that exploded my mind as well. It was just like an M4.

Are all SMGs like this or they vary? What are the options?

I am not sure what you mean? All AEGS use a gearbox. M4's were not the first ones to use one anyway. There are different versions of the gearbox, but most of them work with the exact same principles between them.

M4's use a version 2 gearbox as does Mp5's. The UMP you linked to uses a version 3 as does AK's and G36s.

All electric airsoft guns contain a gearbox, hop unit and barrel. They all do much the same job, and the BB doesn't care what shell they're wedged in, or how the receiver feeds the BBs into the hop as long as everything lines up.

There are a limited number of gearbox "versions", and variants within variants. Parts from one manufacturer A's version X gearbox might not be fully compatible with manufacturer B's version X, or even a different generation of manufacturer A's.

The basic types and what they go in are listed here, if you're interested: https://oioiairsoft.com/gearbox-all-models/
