:blink: Once I had a stuck Stag/CMT gas block. Don't do what I did. I tried to drill out the stripped/galled set screws, but case hardened it instead. I also tried cutting at it with a reciprocating saw. In the end I had to embarrass myself by taking it to Rainier Arms and showing them my work. They told me that I lost my right to build an AR ever again but helped me get the set screws off.
