As many happy people as Bob/Charlie has made with these triggers, Gamo/Theoben should put him on retainer for keeping sales of their rifles moving along!
Both of my CFXs are wearing GRT-IIIs, and they kick butt.
Oh, I also really liked the quality of the PDF file with instructions and high quality photos so even a fumble fingered schmo like me had no problem installing them.
By comparison, a Timney or Canjar trigger for a centerfire will set you back $90 minimum.
