This may sound overly easy but it worked for mine. The trigger in my rifle (actually my daughters),was pulling about 6 lbs. It was a good trigger just heavy. I took apart ball point pens and found a spring about the right diam. and just replaced the trigger spring. I got it down to about 2 3/4 - 3 lbs. Took all of 15 mins to do. I didnt mess with the sear engagement or anything else. Like I said it was pretty good from the start but really heavy.
