Hello, you said you weren't able to remove the camera from the mount. This is rather unusual as I personally own many of these and + various YouTubers are using this mount without issue. Did you remove the bolt attaching the mount to the gun before trying to remove the camera. Also it helps using something (pin punch etc) to push between the two ports on the rear of the camera out of the mount. It is meant to be a snug fit to ensure potential recoil doesn't dislodge the camera.
