Sargenthome.com This trigger mod is older than Methuselah and is an expedient way to upgrade your trigger, despite what the experts say above.
I use RRA NM 2-stage triggers in my ARs, (never paid no $70 or whatever they are going for now days) even have a $200 Jewell 2-stage in my LR AR, but also use JP spring sets for many around the farm here and yes I polish, tweak and do things others above have denigrated and ya know not one person has been disappointed or upset over getting a better factory trigger pull, which helps them shoot better w/ their AR.
JP Spring sets cost around $14 @ MidWayUSA and the link above costs 15 minutes, both work for a lot less than aftermarket triggers which some folks cannot afford and deserve to pointed out to the uninformed.
