Why such a difference in price? NF NXS 12-42x56 cost $1885 versus NF 12-42x56 BR cost $1359. That's a difference of $526. The diffences to me seem to be more cosmetics ie moa turret adjustments exposed-NXS vs covered w/caps-BR and parallax location different. Maybe i've missed something of more significance but from what I can see I doesn't seem to make sense why such a price spread. What say all you NF users.
