That sounds like the “Evolution” Trigger. Quite rare, and would have to come with the action. Fred only sold it if He installed it on one of His ”Blueprinted“ actions.I have one with a 2 oz. trigger, made by and installed by Fred Moreo (Sharpshooters supply) unfortunately he no longer makes them. I also have an accu trigger at 7 oz., but the rest of mine are clunkers, but they are not competition guns either.
