I purchased a RRA 2-stage match and then sent it in to RRA to have them tweak the springs to the lightest available 3.5# which they now call their "varmint" trigger.

This trigger is absolutely incredible. The second stage break it literally a mouse click. That's the best way I can describe it. There's a super positive wall that you feel between the first stage take up and the mouse click break. You can just hold your finger on that wall and click when you want to break your shot.

It's made the rifle so much fun.

I haven't purchase any different pins yet but to plan to pick up some KNS pins eventually. The stock trigger pins work perfectly with the RRA 2 stage triggers and as far as I can tell they're the same pins that come new with the RRA trigger.
