The Ruger 10/22 has outsold them both, combined.
And as far as aftermarket accessories, no other .22 rifle comes close to the 10/22.
Who needs aftermarket accessories when you have a Remington Nylon 66 with a scope?
I agree that in 22 LR there are plenty of other weapons. I have been he Savage A22 in 22 Magnum.
It stands alone as a reasonable priced semi auto in 22WMR.
