Not sure if this review belongs here or elsewhere, so I apologize in advance if it needs to be moved.
The IOR 3x25 QRTS is perfectly designed for SU-16 rifles and flattop AR-15's. The scope is modeled after Trijicon's ACOG line (IOR calling it a Quick Response Tactical Scope). Unlike zero magnification CQB red-dots or holosights like Aimpoints and Eotechs, the IOR is a 3x low magnification scope like the ACOG. Unlike the ACOG which requires separate mounting hardware, the IOR comes ready to mount to flat top receivers.
The scope weighs in at 1lb. Not light, but it balances very well on the SU-16 charlie (with the stock both folded and unfolded). Eye relief is 3.5in., overall length a little over 5.5in. The 30mm tube has a removable 3-slot Picatinny collar for mounting lights, laser sights or other accessories. Mounting is done through 2-12mm hex bolts. This scope is compact enough that you don't need to remove it to breakdown the rifle, and I haven't removed it since zeroing in at the range, so I'm not sure how well it retains zero on reattachment (I'll check that the next time I go out).
The CQB reticle on the IOR is an open-ended donut with a 2MOA center dot. There are also vertical and horizontal cross bars along with range finding mil spacing lines. 2 small circles in the lower left allow for quick reference on targets at 300yds and 400yds respectively (I wasn't able to test this feature since the outdoor range I go to only goes out to 200yds). There are 7 levels of illumination (the center dot and vertical and horizontal cross bars are illuminated in red, the donut is not). The turrets are marked for 1/4 MOA clicks, with elevation adjustments up to 10 MOA and windage +/- 5 MOA.
I like the the IOR a lot. It is one of the best scopes I've ever used. My eyesight isn't what it used to be, and while unmagnified CQB sights like the Eotech are great up to medium range distances (under 150yds for me) I find I need at least a low magnification scope for anything beyond 150yds. Target acquisition was very quick with both eyes open. The IOR works on the same Bindon Aiming Concept as the ACOG. You keep both eyes open as you track the target, and once on the target, your dominant eye takes over magnifying the image (it took a little getting used to but once you have it, it's amazing how it works). I was able to switch between 50yd, 100yd and 200yd targets without any problems.
The IOR is an expensive optic (in fact, I've been questioned on the practicality of putting such an expensive optic on a 'plastic' rifle), but when compared to an ACOG or Aimpoint with magnification, it prices at least $300-$400 less. If you're like me and are looking for something that is quick on target, but gives you magnification for longer ranges, then I highly recommend this scope.
