I am doing an AR build and I am having trouble deciding on a trigger. I have never owned or shot anything with a nice trigger so I don't really know anything about them. After a lot of research I have decided on a Geissele trigger. I am looking at the G2S, SSA and the SSAE, besides price, what is the difference between the three? A little background on the build if it helps. I'm building a 6.5 Grendel and I will be using it for hunting, and hopefully mid to long range target shooting.
