You can find hundresd if not thousands of aftermarket items for 10/22's. Just google search "10/22 Accessories". Here is one site I found. https://www.volquartsen.com/
Volquartsen makes awesome 10/22 upgrades. I have a bolt buffer and auto-bolt release in mine, and I'll be adding a hammer and spring kit soon.
And now I've been totally bitten by the bug (much to my wife's dismay.)
Paul Zint Gunsmith, is there name. I picked up a TS Pac-Lite in red for my wife from them last weekend. They are from Sadieville, KY (where ever that is)
