Cyma M16A4 WE Gearbox Shell?

[Austeyr]

I received my M16A4 from a seller on here today, no issues with it but I knew I had a spare Cyma gearbox with all the bells and whistles (https://www.patrolbase.co.uk/cyma-complete-version-2-gearbox-w-high-torque-motor-and-etu-m4-aeg) so figured might as well drop that into the A4 knowing it would be a heavily used pew in the future.

As I pulled the gearbox out of the A4 receiver, there was a big ol' WE Tech stamp on the side of it - And my Cyma gearbox doesn't fit the receiver.

Confused to say the least. Anybody else have a Cyma M16A4 and can confirm/deny if a WE shell is the norm?

Don't have a cyma but worked on plenty,  never come across a we box in one . 

Why will your cyma box not fit ? 

You sure it's not a we aeg ? ( they take standard v2s also )

Tried a King Arms V2 and also a Classic Army V2 shell and both went in so it seems the Cyma one was the problem. The receiver has a big CE mark and no serial number so it could be a WE tbh. No matter regardless as it's getting rebuilt - Just curious about it really

The Cyma M3 I got had no problems taking the gearbox I got from PatrolBase

It's easy to spot a we rifle,  clear hop unit , stock tube is a 2 part jobby , paint is easy to mark , front pin will not come out etc .

Yep it's a WE then. Transparent hop unit, black lightweight inner barrel, stock has an actual "buffer tube" design (Non functioning of course) and of course the WE gearbox. Mystery solved, cheers bud!
