when i ordered my NM upper from RRA i also ordered one of their two stage triggers. i totally underestimated just how good a trigger this is. i was expecting a slightly smoother military trigger what i got was totally unexpected. My A1 configuration ive heard they were good people have told me they were good but for the money and super easy no adjustment installation this has got to be one of the best values and smoothest triggers available. as you can see its got a different configuration than the standard milspec style trigger system. i missed the initial installation the trigger spring is slightly misplaced but ive fixed that cant wait to see how that rounded hammer design works with a cmmg 22lr conversion. but thats not in the plans for this weekend going to take it out this weekend with the 458 socom and A1 uppers.
