So you know nothing about the Zeiss Rapid Z???
Just happens to be the most advanced ranging reticle in existance. Bullet drop turrets are old technology compared to the Rapid Z technology.
All optics, even the cheapest have so called "fully multi-coated optics." Means nothing. What does mean something is the quality of the coatings and the substances used for the coatings and they all "ain't" the same.
I regularly nail deer with "lethal precision" with simple red dot reflex sights that fit in the palm of my hand and weigh 3.5 ounces with NO magnification.
JMO but I think putting a one and one half pound scope with magnification on a 40 yard crossbow is nuts. On a 22-250 varmint rifle, YES

I use a 4-14 power Conquest Rapid Z that is ballistically programmed out to 800 yards so I never have to touch a turret to shoot out to that distance. Can't see using that for a short range crossbow
So I guess you won't be using any foreign made crossbows in the future?:ack2:
BTW, I forgotten more about optics than you obviously know

Maybe you CAN enlighten me on crossbows though.
