Pretty cool but still needs work.

I would totally buy one when it was working and throw it on my Sendra M16 lower. But this guy posted that video like 7 years ago and hasn't posted anything else after that, so my guess is he abandoned this project.

Holy jumpin jeebus. If you can make that thing run reliably that's gonna be awesome.

Should've used higher brass ammo.

My personal foray into the "full auto 12ga" world was with a Saiga 12 and a light trigger. I quickly learned plastic hulls are no good for rapid fire. I could bump off about 60 rounds or so before the whole shebang got so hot the plastic hulls would melt causing catastrophic malfs during feeding. One big gummy mess would cause the whole platform to seize up until it cooled down enough to pry the melted plastic glob out.

A little research led me to some WWII-era brass hulls but they're cost prohibitive and I kind of lost interest after that. Suppressive fire is handled just fine by traditional MGs. I really like the idea of a 12ga putting down a wall of lead shot but it's one of those deals where the cost far exceeds the practicality.
