..Not sure of the company status, but I bought a TCR22 2-3 years ago, and am eminently pleased with it. It is of course another redo of the 10/22 but so very well done, that I am pleased with every bit of it.
TC started with the 10/22 concept and improved greatly...doing those things, 10/22 owners often do to add usefulness to their 10/22. Strating with a Magpul stock, they add a receiver rear and green fiber optic front sight, with picatinny rail milled into the receiver.
TC pre bores a hole in the rear of the receiver..for easier cleaning form the rear. No need to buy a magazine ejection lever, since it comes with one.
A 10 round magazine with last round stop feature comes with the rifle...but since I never just "fire for effect", I normally use my Ruger magazines, since loading the TC magazine is a PIA (IMO). Accuracy is superb..as I recall, it was about $50 more than the standard 10/22.
Thanking Bill Ruger for the wonderful design, and TC for the added features and much cleaner machine work (IMO)..I hope TC keeps making their TCR22.
If perchance they don't, I'm not worried about parts, since Ruger parts interchange with it !
