You could do a lot worse than MTC. I have a Nikko 4-16x50 which isn't on a rifle ATM (replacement for a faulty one), and an MTC 6-24x56, and the MTC is much better. It is more expensive, but for foxing I would get the mamba range that MTC do, which are in the Nikko ballpark.
That said, Nikko Nighteaters aren't a bad range at all.
