im plenty happy with my 6x42mm NcStar i have a few of my rifles topped with one, and i have had absolutely no troubles with any of them. and they are just as crisp and clear as any of my leupolds and nikons and in low light they work great. though I favor leupolds for their lifetime warranty and the fact they are made in the USA, I just cant complain a bit about NcStar optics.
