Trijicon AccuPoint vs Huron vs Credo 3-9's; how is the AccuPoint so light?

[Begle1]

AccuPoint 3-9x40: 13.4 oz
Credo 3-9x40: 17.0 oz
Huron 3-9x40: 15.8 oz

How is the AccuPoint lighter than the Huron, even though it has all the extra fiber optic business going on?

Would this indicate the Huron/ Credo is of more robust construction than the AccuPoint? Am I missing something? Where is the compromise?

I wish somebody dissected these scopes and showed their internals to understand where some saved on weight.

IIRC, part of the reason is because there is no battery and electronics.

But how are they lighter than even the Huron?

Lower profile turrets and caps... Smaller lower profile ocular housing.
