I love mine. I have the standard two stage on my SBR. Very smooth, light, and all around a perfect trigger. I have never got the gun to fire by slamming the buttstock on the ground. I have seen a few RRA 2 stage triggers fire when you slam the butt on the ground. With teh Geissele trigger, it takes 5 mins or less to install and their is no polishing, smoothing or "final finishes" you have to put on it like some people have to do by buying the cheap other band triggers. It is the perfect trigger out of the box.
With all that said, my next trigger will be the enhanced. I just cant decide if I want the curved or straight trigger for my AR lower w/ Magpul PRS stock and 18" barrel. So for a duty gun, or SD gun the regular Geissele 2 stage trigger is perfect. But for a Bench rest or varmint gun only, I think the enhanced would be better.
