I have modified (3) 10/22s for my own use.
There is no one answer for what or how to modify them.
Here is a book on the topic.
The things to look out for:
10/22 mags are hard to find or expensive right now.
The 22 mag and 17 HMR did now work out well for the 10/22
The 17M2 is not working out well for me in the 10/22, but I have not given up
22 ammo is hard to find right now.
What does it all mean?
There is no final answer to 10/22 mods, it is more of a life style.
