I have found what I believe to be the only other publicly available footage of a Stoner 96 being fired, the other clip featuring none other than Jerry Miculek. The footage appears to come from a TV show and is unfortunately utter dogshit quality.
The uploader has erroneously titled the video to indicate the gun being fired is a Stoner 63.

Ivan Loomis of Kit Badger has put out a video that largely consists of a Q Engineer talking at length about design choices in the new 5.56 Honey Badger. What jumped out at me the most is that Q is using a 1/5 twist barrel, the same twist rate they use in the .300 BLK model.
GunCAD Dev Dinka Roubles has released his Groznt Bullpup AK Chassis. It may not be as good as a Kochevnik, Black Storm or Idlib Conversion but it is a hell of a lot more accessible (especially if you don't live in Ukraine or Syria or know a guy who can actually get you a Kochevnik kit ). 15 Years ago things like these would be manufactured in small quantities and sold in gun magazines by companies that would quickly go bankrupt, with modern technology these can be made by anyone who wants one in theoretically unlimited quantities at a low price both for equipment and per unit.
Staying on the 3D News I have come across two projects that are very intriguing, a Bullpup 10/22 Chassis ala the Desert Tech Trek-22 but with a pistol grip and a project inspired by the Volker VP-33 (a magazine adapter for 10/22 rifles which allow them to use Keltec CP-33 magazines, which can be extended to 50 rounds). Both projects are being undertaken by separate Devs (Damascus2A for the Bullpup, HF Designs for the magazine conversion). Both devs are collaborating to make sure that the Magazine adapter will work with the Bullup Chassis.
Recent thread featuring both Damascus and HF reiterating their commitment to the mutual project.
