I know a lot of you have AR rifles of your own, the stock triggers can be less than smooth. There are several options out there without having to go to a "drop in unit," which IMHO is rather expensive. If you aren't competition shooter, polishing the trigger, using different springs, or replacing the stock group with another milspec kit which has that done for your. The ALG Defense mil spec triggers can drop your pull down to 6 and 6.5 lbs. A lot better than many of the stock AR's which can be as high as 10 lbs or more.
