I cant totally speak on the drop test but I have a 2x12 from 2024 and it has been dropped on concrete multiple times and ridden around on 4 wheeler racks for hundred of miles in rocky nasty bumpy terrain and has yet to lose a zero, even after coming out of the holder and smacking for a few miles on the metal bars. To say i am amazed that it doesn't have broken glass is an understatement. I will give this one caveat - when i first installed it, I torqued the scope rings down to what they recommend and it made my paralax adjustment knob very stiff, called Steiner and they had me back off about 5 inch-lbs due to slight deformation on the tube.
