10/22 on top ,TC22 on bottom
The Ruger 10/22 is an industry leader in the world of semi-automatic .22LR rifles. However compared to the AR-15 and all its clones, there are very few alternatives to the venerable Ruger 10/22. Sure you can get a Volquartsen or a TacSol X-Ring but they are both near the $1,000 price range. Affordable 10/22 clones don’t really seem to exist except in the past like the AMT Lightning or the RIA M22. Well Thompson Center has their own 10/22 clone, the T/CR22 and it is not only affordable it is better than your stock 10/22.
