It's a Vanguard Submachine Gun! based on the Heckler & Koch MP7.
I'd say it's suitable for use in a science fiction game/environment that's still grounded in reality.
Textures are 4K, Formatted in PBR, Unity and Unreal Engine.
The total vertice count of the gun and all attachments comes to 41,912.
Feel free to request a format! I am also open to commissions. :)
