BA-10, a bolt-action shotgun

Enjoy this brand-new sidearm-shotgun from based on fav.me/d8933d3. It's primarily single-shot bolt action, and not quite sure how it works but I think springs are involved (Duality please confirm). Apparently it'll take all sorts of fun 10 gauge rounds, including metalstorm and one of my own design based around a flying WASP injection knife (that never made it to the 3D modelling stage), but has the most fun with good ol 10 gauge buck-and-balls. Also one of the first guns outside my first that I experimented with weathering.

Made in Cinema 4D in... oh... 4 hours?
