The JP spring kit may work for you. Installed the kit on my RR but had to remove it quick as it gave light primer strikes. Since it goes for only $10 or so, may still be worth a try on your rifle. Went for the LaRue trigger kit, and like it fine. The LaRue kit is a milspec design made as good as it gets. Best steel, best machine work and best finish. They advertise 4.5 lbs, mine breaks right at 4, smooth and crisp. Might be just what you are looking for.
