There are books dedicated to that question and I should get one of them too. I've always wanted one and couldnt justify another gun, or fit another one in my house. I lucked into a trade earlier this year and have my first 10/22 and love it, they can be built completely from aftermarket parts, there are so many manufacturers, I guess theyre the harley-davidson of rimfires. What do you want to do with your gun?
