We tried hard to kill this gun, but it refused to die. We tried, but it just wouldn't fail. On the third part, the gun is held with a sustained auto burst of 2:30. We were all sure the mechbox would melt down. A few times, we smelled burning plastic, but despite that, it kept going.
After shooting this video, we loaded up a mag and fired it through the chrony. It still shot at the same 220-240 fps it always did and performed exactly the same in semi, only with an incredible responsive trigger. We tried but couldn't measure the rof as at that speed, the BBs wouldn't feed consistently.

This was shot with my Panasonic Lumix camera, so the video quality isn't great, especially in low light. But you can see and hear everything clearly.
