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.

Best LPK on the market

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.
