Need your thoughts on a trigger for my needs.

[Variable]

While I've never used the Rock River trigger in my own rifles, I have put them in builds for other folks. They seem relatively decent for the money. IIRC-- They don't have as good of an internet rep for longevity as a trigger like the geissele though. If you want the top trigger for the moment, I'd have to say go Geissele. They cost a lot more, but are in a whole 'nuther class if the budget allows it. I have KAC match triggers in my rifles, but after having one come out of adjustment I'm leaning heavy towards replacing them with Geissele triggers myself (as my budget will allow).
