How can I take the gritty,drag and lighten and bring my Colt 6920 trigger pull down and somewhere close my two LMT's M4's and my Doublestar lpk I installed. I will post back later after I use my trigger pull guage and see what the the trigger pull reads,feels like 12-15lbs. I see a photo showing where to stone and polish the trigger, sear and disconnector
