Our barrel is mounted to a metal section of our arm. We used a couple of large hose clamps, also metal. By looking carefully at the design of your bot, you should be able to determine if your attachment point is electrically connected to your chassis or frame. If it is, a chain or other conductor attached to the frame and dragging on the ground should suffice. Remember, high resistance in the path to ground isn't that big of a problem. For instance, an anti-static mat and wrist cord measure around 1 meg. ohm between the wrist-strap and the mat, and another 1 Meg to the ground clip. You don't need, nor necessarily want, a short to ground. Just make sure you have a conductive path from the barrel to ground that bypasses the electronics.
