All the big, bulky, heavy AR-22 options and they are all still trumped by the efficiently designed, much less expensive basic 10/22.
yourself!
Not trumped, just different. Like having two different styles of hammers. An AR shooter will like the AR in 22LR for cheaper training (well, when you can find the ammo, if you don't have a stash ), and the 10/22 for squirrels or target shooting. That's what I do, anyway. I have both (more than one 10/22; they are like rabbits...)
