The trigger pivot and location of the spring probably dictate higher than "normal" trigger weight.
But, that might be based on the factory spring.
The Rifle Basix trigger has the trigger spring moved inward, think that probably why they can adjust lighter.
Not worth experimenting IMHO, I got mine usable. I like better triggers, but then why not get one for a better looking rifle?
To me putting in more work/$ into an Edge/Axis is like putting lipstick on a pig.
