RRA 2 stage NM trigger is (IMO) fantastic, for the price.
my father has an AR gold in his precision rifle, and that thing is a dream and a half to shoot. problem being, it costs about 3x as much IIRC.
for $100, IMO you cant go wrong with the RRA 2 stage. i have seen people who have ended up with issues, but plenty of folks with no issues. mine was worry free for over 5k rounds while i owned the rifle.
I have the RRA 2 stage in a number of AR's, the first thing I do with them is always switch the springs out for the yellow JP springs. I have had nothing but great luck with them. Another trigger that I use is the JP that I haven't seen anyone mention so far, that single stage trigger has gone thousands and thousands of rounds, and is still fantastic.
I forgot to update this thread. I did pick up a RR NM 2 stage trigger for my budget AR. Took it over to Parabellum a few weeks ago and ran a couple hundred rounds through it. I was happy enough with it I ordered another one for my DPMS G2.
