Upon the recommendation of my buddy who ownes everything from S&B, Nightforce, Zeiss etc in the US I picked up a 6-24X50 with 35mm tube.
The glass is outstanding and the adjustments are positive and repeatable. The love illuminated MP-8 recticle . I have a S&B PMII and Nightforce NSXs and MK4s to compare with
I take what I read on the internet about IOR complaints with a grain of salt. You get the vocal minority complaining. Talk to the guys at SWFA or Bear Basin and they have lots of repeat IOR customers.
Snipershide.com is a good place to get info on IOR
The only truth to the complaining is Val, the customer service guy is not the most reasonable to deal with. I made a mistake and ordered the wrong height 35mm rings. Val had no problem replacing them but he just wasn't all that pleasant. Fortunately there is another CS guys who is way nicer to deal with and very informative. The replaced my rings for the proper height no problem.
I truely believe that Nightforce and Trijicon makes outstanding proven optics but the only problem I have ever had with scopes was a NSX that had a loose flake floating around inside from day one, and a Trijicon that had tritium illumination issues. Trijicon was a huge PITA to deal with. I haven't sent my NSX in yet so I don't know yet. It wouldn't be fair to conclude that Trijicon makes bad products just because I had problems
BTW I couldn't find Willys name or contact info either.
As far as durability, I put this scope on my 338Lapua with brake with no problems. It currently resides on my RRA Varmint though . Managed to drop the scope once even
My only beef is the goofy 35mm tube. I have a 30mm and 34mm lapping tools but no 35mm so I couldn't lap the rings. I hate oddball size tubes !
Bottom line is I will buy another IOR without hesitation. Excellent value for the $$ . The only scope I would trade my IOR for is a S&B PMII . The S&Bs are twice the money btw
