Here is a good up close video of the sound. Sounds to me like an AK-47.

You may have to click the speaker on the video to hear it.

That’s actually not that good. The phone microphone is clipping the shots pretty badly due to the sound pressure levels at that distance and angle - there are other videos where you can hear the firing better since the microphone isn’t clipping.

That’s .30cal fire.

Maybe. small microphones can miss portions of sound spectrum?

The only times I've heard full-auto AK (7.62x39) it was harsher, and heavier "crack-crack-crack-crack". Made my hair stand on end.
