Yah 10/22 is really a hard to beat rifle. A Marlin .22 comes close as far as price but it is not nearly as reliable. I was raised on cylindrical loading though lol. All in all ruger does a really good job on their rimfire firearms.
the take down version (in blue polymer no less), is a pretty hot option, if you want an all weather, compact solution
various other companies make so manu upgrades from "ultra triggers", to completely new uppers - like carbon fiber barrels!
even some of the "high end" guys, like magnum research. go nuts.
plus Ruger makes some nice options - a full all metal nordic kit version, with collapsible stock (actually good for kids), and has some mass for stability, and option for suppresion or other front end accessories
it's a fairly iconic rifle.
that said, i LURVE the SIG 522. damn fine rifle. lots of fun. it's a good thing. basically a SIG 55x trainer, but by itself, is a gas to shoot.
or the S&W iirc, it's basically an AR15 training platform with nearly the same ergos.
the RANGE of .22LR rifles now, and even a few .22 WMR is pretty cool.
i WISH WISH WISH KELTEC would get off their duffs and produce the RMR-30 already. so does Ethan ;D
