We spotted the Ruger 10/.22 Takedown at the SHOT show two years ago, and Bill Ruger’s stepchild has certainly thrived since then. While the scarce little rimfire is certainly not lacking in awesomeness, there’s something to be said for an adjustable-length buttstock. Especially on a rifle that’s so ideally suited to younger, smaller shooters. Don’t worry: Tapco is all over it . . .
