HA! Just used these videos to smooth the trigger, install a Short Reset Trigger and a Race Hammer from Cajun Gun Works.
Between this excellent tutorial and the incredibly well made and easy to use and install products from Cajun Gun Works, I was able to get this hammered out in one evening. This from a guy who's background in gunsmithing is basically replacing a firing pin and a trigger spring in a Colt 7.62x39 AR. I am super stoked. I can't say enough about the customer service from David at CGW. I will definitely be giving them my business in the future and would recommend them to anyone.
The only creative criticism I can give the video series above is that by trying to remove the right side decocker lever, I tore up the bottom of the lever a little attempting to remove it as he does. I found that by applying opposing force with my thumb on the opposite side of the lever just on the other side of where the detent lever spring thing that you push with the flat head, made removal of the lever much easier.
Good luck. If I can do it. So can you.
