Tactical Sh*& did the videos. so I cannot link on here due to the filters, yes it filters links too. They have them up on their youtubes and facebooks. I do not like tactical sh*& as a company for reasons, but they run 5 or 6 mags full auto with no issues in one video and 3 or 4 full auto in the other with no issues, no earplugs, and no eye protection... I don't think the video is lying. I don't need a full auto or even one that can handle extended periods of rapid fire. I definitely don't have the cash to be a regular mag dumper. Something to calm the rise, lower the noise, and handle my maximum use, while being relatively small and low interference with carbine operations, I think it fills the bill. witt machine is pretty stand up, they answer the phone and their integrally suppressed uppers are well received.
