Nice kit!
Installed the spring kit with the OEM trigger shoe. The Ech already has a wonderful trigger to begin with…even better with this kit! I don’t have a pull gauge but it definitely knocked some weight off. Install was really easy after giving the video a watch.

Echelon Trigger Spring Kit
Watch the video on YouTube. Watch it again. Installation was challenging but not too hard. The spring kit reduced my trigger pull by 1 lb. 4 oz. The reduction in trigger pull was worth the effort.
