It won't be a problem to get 12fpe from the 800, you would do it in a similar way to the Anschutz 8002 & 9003 etc. All I meant was it's not going to be an off the shelf tweak like the Steyr & lg300 & 400 Walthers. It Will take a little bit of work, if it's your thing that is!
Oh & by the way, lf your going to mod the Tesro RS100 don't forget to upgrade the cocking link pin or it May well break. They are prone to break anyway.
