It would probably freak some people out. I did it with the tripod legs extended far enough for standing position, but all 3 legs together. The rifle was clipped in and I was only holding the tripod legs with the rifle just hanging over my back with the muzzle pointed up (nothing in the chamber). The only thing keeping it from falling was the Anvil head clamping onto the rifle's ARCA rail which I trust completely.
Basically like this but with a rifle and not a camera. In a flat prairie there wasn't really a concern of it catching on anything so it was nice for short distance repositioning for my shot.
