i bought the jp enterprises fire control system trigger spring kit 4.5 (not the yellow 3.5 spring kit) installed it in my smith and Wesson M&P/magpul (co branded lower) mid length ar 15 today. without polishing or anything the STOCK trigger is averaging 6 pounds with the lyman trigger pull scale. I thought I would get this kit and pay $10 bucks and lower the pull to at leasy 5 pounds. wrong, after installing it was averaging over 7 pounds! every review I have read say they work but it actually made mine worse. I guess I was expecting a miracle trigger for only $10. yes i installed them right, 2 separate times just to make sure. oh well what can you do...
