Got my 3 1/2 lb. JP Spring kit for my AR yesterday. Had watched several you tube vidios and thought l had it down. After getting sear section out l started on the trigger. After getting pin out and wrestling with it for 10 mintues, l realized it won't come out without removing the safety. After finally realizing l had to remove the hand guard to get the safety out everything went great. My 7 lb. trigger is now about 4 lbs. Would have liked a 2lb. Trigger but for 12.00 it will work. Don
