Hey, I am looking at 'freshening up' my mom's 10/22. It's about 30 years old. I don't plan on making it super accurate or spending a ton but just a new barrel and stock. Where is the best place to get replacement parts? Any thing else I should replace if I'm going to have it all apart already? I'd don't know anything about 10/22s. Just looking to help my mom out, maybe make it a little more accurate in the process. Thanks for the help.
