I'm pretty sure about the rate- with video editing software I'm sure I could get an exact number- but it's in the ballpark of what I stated. Actually- in full disclosure, we used a Timney single stage, 3lb trigger- likely a significant factor. I couldn't tell the difference between the M16 on full auto and the AR with a Slidefire stock. There was at least 10 years difference between shooting the two, so I could be off on that comparison, but I'm confident about the rate I calculated.
