So my dad recently handed-down his Remington 521-T .22LR bolt-action. His dad bought it for him when he was eight. My dad carried and shot the fuck out of this rifle during childhood, so to say that it's seen a few rounds would be the understatement of the century. It's the first gun that I ever fired, he taught me to shoot with it. So, to say that it's special is also putting it lightly. Cosmetically, this gun has seen better days. The outer barrel, fixed front sight, bolt handle, trigger guard, sling swivels, etc. are pretty badly rusted, they have a deep orange color. I'd like to take the rust off and restore this gun to some of it's former glory. It still runs like a champ. Does anyone have any experience with this kind of procedure?
