Here is a Black Friday video bonus for our Daily Bulletin readers. Today we showcase three of the most amazing 3D “cutaway” gun animations ever created. Watch the operations of a pump shotgun, bolt-action rifle, and semi-automatic pistol. The superb cutaway views show details of the firearms’ internal parts, and show how ammunition cycles start to finish. Each of these videos took hundreds of man-hours to create, and each has been watched many millions of times.

Folks, if you have any interest in shotguns you should definitely watch this video start to finish. This shotgun video has received 3.9 million views in just 10 days!

The video’s talented creator, Matt Rittman states: “Cinema 4D was used to create each individual part, as well as animating everything. Substance Painter was used to create the wood stock and fore-end textures. Corona renderer was used for final output of lighting and textures.” See more of Matt’s 3D videos on his popular YouTube Channel.
