In its current state, when the Charrzooka is holstered it clips through the ground on even terrain. My suggestion is to move the “fulcrum” point (the part on the rifle that is anchored onto the center of the character’s back) down the barrel in the same fashion as The Hunter. If you notice on The Hunter, the stock of the rifle is farther over the shoulder than any of the other rifles because the “fulcrum” is a little further down.
It’s a minor issue, but I think it would make the weapon a lot more pleasing to carry around.
