Shooting Rem 223 i never had an issue with this, but with Aguila 5.56 itís definitely a thing. I record both myself and my targets so i can pick out things Iím doing wrong with handguns. I left the camera on today with my AR and every time I shot it blurred the camera. Though obvious in the video, the still image when pausing the video shows that the entire image blurrs when the muzzle breaks after the shot.

i guess what Iím getting at here is that Iím amazed it affects the camera from over 20 feet away.
