I'd put the bolt body in a heat sink, heat the bolt shaft with acetylene torch and bend it. Acetylene because it is hot and fast heating, minimizing heat transfer to the rest of the bolt- hence heat sink also. Take about 10 minutes for the job. If you can't, take it to a gunsmith, welder, or machine shop..
That's what I'd do, if it were mine. That bolt knob sticks out like a sore thumb right now. Bend the sob down and then go with and even lower set of rings...JMHO..
