This is a very nice parts kit. The 2 stage trigger delivers as promised and breaks cleanly at 4.5 lbs total abd has an excellent reset. The finish of the parts like the safety is also great.
My reason for 4 stars is my kit was missing the trigger guard roll pin and contained 2 roll pins the size for the forward assist. I had another on hand so did not contact Stag but I have no doubt they would send to me. It was just inconvenient that it was missing.
Sweet trigger! I seen the reviews and said to myself, self, this trigger comes with a build kit and has good reviews let’s give it a try. To my amazement this trigger is a keeper. I will buy another.
Great LPK. All parts were free of burs compared to other kits I've purchased. The two stage trigger has one of the best feels of any non custom drop in trigger system on the market today.
The ambidextrous fire control switch option is a great way to finish your build.
First came across this trigger in my Model 6. I've been ordering them for almost all of my customer builds. I've installed plenty of Timney, and Geissele triggers. None have felt as good as my Stag model 6 though. It shoots a ragged hole, no matter how many rounds you send down range.
I have 2 rifles with this trigger and I recommend it to anyone building an AR. The fact that they offer the lower parts kit with the upgrade now is a huge bonus. The first comment from anyone who shoots my rifle is, "I love that trigger!" Great value.
Very crisp smooth trigger pull and very well priced. considering most places want 120 just for a 2 stage trigger group. This is a great deal for a whole LPK.
