I own a Swaro Habicht 6-18x50 AO with a BRX reticle. They're not low end glass is great better than the Z3 mine is on par with a Z5. I can't imagine there is a Bushnell scope out there that compares especially not for 600.00 but I will look.
I have been trying to sell mine I want to get a scope with target turrets.
If your interested send me a PM.
Good luck and shoot straight
