Like anything, it's all personal preference - I simply prefer Geissele over Rock River. I absolutely agree that Rock River is a huge improvement over mil spec.Ah, but then I'm not exactly a 'sensitive, new-age kinda guy' so I probably can't discern the difference. My buddy who has a Geissele 2-stage in his AR has commented that he likes the feel of the RRA also. At any rate, it's a marked improvement over a basic trigger.
