Tracking is extremely good, albeit the turrets are too easy to spin in my opinion, would have liked more resitance (the cilcks were somewhat mushy feeling). But the clicks do settle in nicely and have never moved on their own.
The adjustable objective is a dream to operate. They say its 180 deg turn but its a bit less than that in reality. Its the perfect amount of resistance . I don't feel any need for a side focus when operating the AO on this scope.
Overall finish is good on the matte black versions, silver finish is a bit hokey.
Turret caps feel a bit thin but sturdy none the less. Magnification ring has same outstanding feel as the adjustable objective.
The eyebox adjustment is the standard threaded type with a lock ring. It is a fine thread that requires quite a few turns. I had to turn it four times before checking or I wouldn't see any perceptible difference while focusing the reticle.
Hmm what else. The glass is the best I've used (during day), which is to compare it to a Leupold VX-II, Vortex Diamondback, Bushnell Elite 6500, Burris Signature Select and a cheapy Simmons (obviously).
Have not extensively tested it in low light conditions, but I would say it is about on par with the others, doesn't particularly stand above or below any of them.
Feels very well constructed and made in japan.
