A splice of MP5, G36, AK and other bits and pieces.
Anyone fancy modelling this one? I'm fairly sure all of the parts are available, you could probably duct tape this from models lying around in the devhub.
It's a gas operated 5.56x45mm assault rifle with similar internals to the AK47.
I'd call it a 40/40/10/10 split. MP5/AK47/G36/M4.
It's an assault rifle, and it looks pretty good, what more do you want?
