Asked the same question on another forum and got the same answer. Apparently no source of parts for the TCRs. Whole rifles and receivers occasionally show up on the auction sites. Bought a rifle sold "with issues" awhile back. Traded the barrel and stock off and kept the receiver as a source for parts. Did find that the little extractor spring you need for rimless cartridges is the same as the one on the Encores. Numrich lists the spring as available on their website. They also sometimes have stuff they don't have listed. Wouldn't hurt to call and ask if you need something;. Not much help, but apparently the best we can do.
