Very smooth and tight. definitely recommend. - OpticsPlanet Exclusive HIPERFIRE HIPERTOUCH Blue Line Special Edition AR-15/10 Trigger Assembly

I've built 9 ARs and, along with the mil spec triggers that come with many lower part kits, I've installed many drop ins. This trigger is not a drop in and started out quite easy to install. The HIPERFIRE instructions stated I should view their video online BUT there is no video that I could find showing any installation technique. So I went with the few photos and instructions in text. I took me a few times of installing and uninstalling to start over. The issue was the "U-bar with the 2 springs" Afterwards I figured out how to install the U-bar correctly and then add the 2 springs. I can now install one in about 5 minutes. It's very simple although, for the first timer, it may require some patience.

Brought the rifle to the range. This trigger is impressive. Smooth, light with no travel what so ever. I like the straight trigger and have another rifle with one but this one has that blue shoe. It really makes a difference for the better.
