Well I didn't think it was taking a chance. Maybe quality has tanked in the last few years but my instructor (USMC sniper, Army Sniper instructor and contractor) in '08 was a big IOR fan and had one on his M40A-1. I had never heard of them prior to that.
I have been told to 'avoid IOR' but in my searching I don't see anything beyond the typical failure that happens with any production item. If you have a bad experience with a Ford you never buy another one, but there are a bunch of others that run years with no problem.
Im trying to get a perspective on things- is it chronic 59% of them "fall apart" or was yours an unusual one?
on a positive note, before it failed, did it hold zero well? Was it as bright and clear as I would expect it to be with such a large objective?
im thinking this, or an ultra 10X which would then move to a future M24. Im sure your vote would be for the Ultra but back then (and several reports since) they were having trouble holding zero with Leupold. And to get a fixed 10x56 with target turrets from them, I'd be waiting a long time I think. They got a bit funny about selling their ranging reticle and "tactical" models in general...
anyway, thank you for the reply, and if you'd care to elaborate on "fell apart" I'm all ears (or eyes as it were).
Thank you!
