Thank you for the offer. I do have a Geiselle trigger on an AR10, and it is very nice! I know a spring kit isn't going to duplicate that trigger. My AR15 trigger must be over 8 lbs. It is horrible. I just would like to lighten it up. If I could get under 5.5 lbs, I would be happy. I am not trying to turn the AR15 into a DMR.
Buy a reduced power spring as mentioned and I’ll let you ty out this grip screw if you’d like. It will help you remove almost all the creep with a nice clean break. For the $20 it’s about the most cost effective and on most triggers it’s been more than enough to satisfy.
