A recent 3D gun concept from my piece Apex Predator. It's called Panthera Gun, a kind of compact heavy rail gun. Done with SketchUp and rendered with KeyShot. Actually it was just my attempt to trying render with KeyShot, no intention further than that. Also, it's been ages for me since the last time I'm modelling something, so yeah pardon me for the ugly looks.
Anyway, thanks for looking.
