The joy of the 10/22, you can change everything on them!
You can spend as much as you want and buy some very fancy upgrades.
Simple stuff helps improve operation and manipulation.
- Replace the steel recoil stop with a polymer one. Tuffer Buffer is the brand one. Smooths the recoil.
- Volquartsen EDM extractor
- Volquartsen sure strike firing pin
- Extended bolt handle
- Automatic bolt release
- Extended mag release
You can work on the trigger, but results can vary and it is easier to swap it out in my opinion YMMV. The Ruger BX trigger is a solid upgrade with the bolt release and mag improved. You can spend a lot of money here if you want with things like Timney, Volquartsen and Kidd.
Stocks and barrels, world is your oyster. Ideally its best to get hands on with them, other shooters may be kind enough to let you shoulder their rifles to see how they fit you and balance in hand to get an idea of what will work for you.
For stocks on the 10/22, I like the Hogue overmolded ones, comfortable and grippy.
In relation to barrels, I found 16.5” bull was the right balance, the carbon fibre and graphite ones were too light. Consider ones with the 'Bentz' chamber which should give a happy medium between accuracy and reliability.
Best thing is, if something doesn't work you can just swap it out again!
