Identify this Mechbox Shell

Hey guys, I have a mystery mechbox shell that's lying around here.

I'm wondering if anyone could help me identify what brand this is.

I've currently ruled out TM(No serial number on this mechbox shell unlike the TM), King Arms, Systema.

Turns out it's Systema

It's reinforced at the rear. No markings of any kind except for a "9" inside the mechbox shell like shown in the picture. Bushing size seems to be 6mm.

Yes! Thanks Mark!

looks exactly like the G&P 7mm except for the charging handle tab on top

It's a ProGear. (ProGear = Systema)

I've seen this exact same gearbox mould sold under other brands as well, though off the top of my head, I can't remember the brands. I have a feeling it was G&P and/or Hurricane.
