I put a calvin elite in my 700. I've been super happy with it. Taking out the stock one was a pain.
Some people say to avoid certain aftermarket triggers that don't perform well in dusty environments. That may be worth looking into for yourself. The only trigger I have had an issue with acting funny while dirty was an ar with (I think) a Chip McCormick. I think the suppressor helped foul it up and it wouldn't reset consistently.
