372,000,000 views! Today’s five feature videos have, collectively, been viewed 372 million times on YouTube. Today’s Saturday special features five remarkable animated firearms videos from Matt Rittman, a very talented computer graphic artist. Matt employs multiple software programs to create these incredibly detailed animations. His software tools of the trade include Cinema 4D, Substance Painter, and Corona renderer. Don’t think this is easy. Some of these videos took over 500 man-hours to create. Enjoy!

AR-15 Full Animation — Components and Function

While there are other AR-15 animations on YouTube, we think this is the most accurate and creative, showing the function of a wide variety of components, including the bolt carrier, extractor, trigger, stock buffer, safety system, forward assist, and mag release. It also shows modes of a military M16, showing 3-round burst fire, and full-auto, employing disconnectors and auto sear. If you are planning to assemble/disassemble an AR, this is definitely worth watching start to finish. This video has recorded over 2 million views in just three weeks!

Glock 19 (Gen 4) — Inside and Out and Function

This 3D animation video shows the popular Glock 19 (Gen 4) pistol. This modern, polymer-framed, striker-fired pistol has constant trigger pull for all shots. Some folks call this a DAO (double-action-only) trigger but that’s not really correct. Unlike the Model 1911, on a Glock there is no external safety on the frame or slide. The trigger “shoe” (the part that contacts finger) includes a central blade. This prevents the gun from firing unless the trigger is depresses normally. Glock calls this the “safe action”. The 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 main textures. Corona renderer was used to render everything. This animation [with 84.6 million views] took me over 500 hours to create.”
