My grandpa asked me to look at one of his 22’s he hadn’t shot in decades, said it wouldn’t cycle right and asked if I’d take it apart and clean it for him. I wasn’t expecting the rifle to be in as poor condition. I’ve never dealt with anything this bad before and I’m just wondering if it’s still safe to shoot, and what my best bet is for taking away some of the corrosion if it is.

Thanks!
