my vortex viper is much better in lowlight than the Nikons ive got on other rifles. You cant go wrong with vortex for quality or warranty service they are strait up no hoops to jump thru on the rare instance you may need service. I cant say the same thing about Nikon. Vortex is now my go to company after using Nikon, Leupold, Bushnell, a few cheap tascos somewhere in the mix ive been happier with Vortex over any of them.
