There are Gieselle's for only incrementally more than the RRA NM triggers, and they ARE legitimately better than the RRA. The G2S is $130 on sale at Brownells right now. I'm using a G2S-E in a customer rifle build on which I'm currently working, which are on sale now for $150, and it's a notably better trigger than the RRA NM or NM-V.
The hi speed NM 2 stage is a pretty penny, and worth every bit, but it's understandable not everyone wants to put a $250-280 trigger into their carbine. But there are cheaper options of insanely good quality in Gieselle's line up.
My favorite 2 stage trigger of the past, cheaper than the Gieselle NM 2 stage, was the Bushmaster NM 2 stage, but these are rather high priced when they can be found, and frankly, just can't be found most of the time.
One important thing to consider - not all 2 stages are designed with the same spread between the stages. The Gieselle and Bushmaster triggers are a heavy take up with a light break, a good surprise break trigger, whereas the RRA design (inferior in my opinion for precision shooting) is light in the first stage with a heavy wall. The RRA design is nice for a guy who likes a heavier trigger and wants to feel his finger on trigger before the break, basically a guy who wants a single stage trigger with a little more sensation. But if you want a surprise break, the RRA design falls behind the others. Still a good trigger, and I'm happy to use 3 of them in personal rifles, but it sure isn't on par with a Gieselle G2S, let alone a Gieselle Hi speed NM
