I like those Tech-Sights. That’s the thing with a 10/22, you can get tons of after market products.
I went cheap a few years ago and got a Savage 64. It didn’t cost a lot of money, but it just does not compare with the 10/22.
I recommend you get one of the polymer buffers too. Makes shooting a lot quieter.
