I'm refinishing my grandfather's 97t in memory of him. Back in the day he got rid of the heat shield and bayonet lug, drilled/tapped the receiver and added a scope/mount to hunt deer. I want to get a repro heatshield/bayonet lug and take the scope off, but there are ugly holes left behind. Is there a way to fill these holes? Would I have to get a MIG welder and park the entire gun? I need some advice. Thanks guys!
