I own 2 of these now for a Howa in .308, and a DPMS in .223. Even in low light I can pick out a set of coyote ears against a backdrop of dead grasses at over 300 yards. Bright, crisp glass. Zero never varies. I use them at night as well with only moonlight. Great stuff.
Pros: Extremely clear, crisp, and bright in low light conditions.
Cons: Might be pricey, but it's Nikon, and therein lies the value.
