Was messing around cleaning the 223 barrel that came on the TCR 83 I bought not too long ago. Extractor looked grungy when extended out so I removed it and quite rusty inside the slot it moves in. In fact the cartridge end of it almost looks to have been rewelded, modified or something? Are there and parts at all such as this available anywhere? It works fine but just curious if anyone knows of any small parts sources? Thanks.

Respectfully,
Dennis
