I don't think most would like the hammer mounted safety on the KRB7 (if they were honest about admitting it). Knight should have simply used a rebounding hammer as they did eventually with the KP1. That safety just seemed flimsy, weak, and unnecessary (it IS necessary in THAT design though). I also found priming the rifle to be a little tricky.
I saw one on the shelf at Bass Pro that had a broken safety spring. This made the rifle completely non-operational. I pointed out the problem to the person "working" that counter and that person simply sat the rifle back on the rack with the other new rifles. DOH! Beyond the obvious lack of concern at Bass Pro, the mere fact that one tiny little spring in that hammer safety (which I considered a dumb design anyway) can make the rifle useless impressed me.
The built-in takeup on the KRB and KP1 triggers is something I never cared for as well.
