I just picked up a Hensoldt Fero Z-24 scope made in 1986, used an ARMS throw lever mount and put it on my AR. What a surprisingly good optic for a 16" AR. Anyone have any experience with these scopes? Though 25 years old, this new condition Hensoldt has great optics and appears to be very rugged. I have a Trijicon ACOG TA-11 on my other AR which is a good set up but this old German scope really impressed me.
