Can someone who has sound-editing software analyze the following clip (particularly near the end) and get a rough estimate of the QBZ-03's rate of fire?

I can't do the editing but generally the QBZ03 is listed to have a Rate of fire around 650-700 rounds per minute, which is abut the same for a QBZ95.
Which is about the norm for a modern Assault rifle. I mean there are some exceptions like the SAR21 at a very slow rate of fire 450-550 or as ridiculously fast as the 2 shot Hyper burst of the AN 94's 1800 rpm.

The audio is not the best defined but I did it both audibly and visually by frame timecode through my video editing software. I count 6 audible shots. Visually, counting from the first 'muzzle flash' and subsequently until the frame (0.02 seconds per frame) just before the final movement of the operating parts (Audio too ill-defined to use to time, and no defined visual muzzle flash for last shot to use as time marker) was a time of 0.355 seconds. 6 shots in 0.355 seconds = approx. 1014 per minute. +- 0.04 seconds. So 1002-1025 rounds per minute approx. , or just to account for realistic error, 1000- 1030 per minute. Hope that helps! :):)

To be honest the 650-700 rpm figure isn't really supported by any credible sources, and judging from other videos of AKs and ARs, the QBZ-03 definitely has a higher rate of fire than merely 650-700 rounds per minute. If you compare videos of the QBZ-95 in full auto and the QBZ-03 in the clip above, there is noticeable difference even though Wiki lists the same ROF for both.

Thanks for your work; that is incredible! :D

Again, this is under the assumption that QBZ 03 not modified. A difference of 300 or so rounds per minute is quite a deviation from the 650-700 mentioned by Terran_Empire is quite significant but cool nonetheless.

Are there any modifications that would increase its ROF by such a magnitude, though? I feel that the 650-700 rpm figure is either outdated or outright incorrectly adapted from other Norinco rifles.

Springs and gas parts modifications. I will see if I can analyse other clips to account for possible error.

That's a possibility for sure, but how likely are we going to see modified 03s at a civilian gun range? I'll look for other clips of the QBZ-03 in full auto.
