I've only fired one AR and it was my brothers which had a custom trigger. It seemed to be a single-stage trigger that had no takeup, no slop, and broke like glass at a nice low weight. All that kinda spoiled me and I'd like a nice trigger on my AR build. I've been looking at different 2-stage triggers. Seen some from RRA, LMT, and other names. I assume these are easily installable just like a normal LPK, correct? Anything I should look for or avoid? Any other advice to give for a relative AR noob? I really wish there were some examples around here I could dry-fire.
