When I was "customizing" a 21 for sc use, I read some of your posts regarding foreend issues, and made mental note of them, that's all. I thought you might like to share your wear and repair experiences with those considering a similar effort.
I don't know if CSMC warrantied the repairs, or charged you for them under wear or abuse.
If I am mis-remembering the posts, I apologize.

Out there doing it best I can.
