I don't own a 10/22 and haven't used the Ruger charge handle Rimfire Technologies sells, but I have used several of their Marlin parts on my 60. The Marlin parts are excellent quality, the Ruger charge handle should be the same.
Rimfire Technologies Charging Handles
The guys and gals at Rimfire Central will have a lot more information on the Ruger and just about everything else rimfire related. They probably have several members who've actually used the R/T charge handle and can give you a much better review than I can.
