I have to laugh. Buy a Ruger, change the barrel, change the trigger, change the stock. Whatcha got? It ain’t a Ruger 10/22. Man buy the gun ready to shoot out of the box.
You still have a 10/22. The action defines the rifle. A Remington 700 with a Shilen Barrel and a Timney trigger is still a Remington 700.
10/22s have reliable, plentiful mags that do not destroy the driving bands on bullets; a trigger group that makes improvements simple; and a bolt/barrel block interface that makes swaps and headspacing super easy. For some reason, you're imagining that the "ready to shoot gun" that fits someone's (i) personal interests, (ii) intended uses, and (iii) budget even exists.
Remember, most factory "match" semi-auto guns, even those with heavy barrels, have generous sporter chambers. The average consumer will probably shove Stingers in there at some point, so the factory wants to make sure they'll function. Those guns will also have triggers made at a price point. Add in the typical "jack of all trades, master of none" stock, and you have a gun that's not ideal for bench, bags, bipod, or offhand, as the particular sport/discipline might need. Why buy a less-than-ideal, but more expensive, turn-key option?
Want a 10/22 in a chassis with a 4oz/4oz two-stage trigger and a threaded 16" bull barrel? You can build that. Ruger doesn't make that from the factory. No competitors make that either.
Want a 10/22 in a Claro Walnut stock with a 24" sporter barrel and a 2.5lb hunting trigger? You can build that. Ruger doesn't make that from the factory. No competitors make that either.
Want a 10/22 in a superlight stock with a carbon-wrapped compensated barrel with a 1 lb single stage trigger built for Steel Challenge? You can build that. Ruger doesn't make that from the factory. No competitors make that either.
