The 3-15 is the classic series, they go to 5-15 in HD. If they had a 3-15HD that would be a consideration but I need more low power than high in Georgia. I have one of their 1-4 scopes and frankly was surprised when I got it regards what you get for the money.

On the NF 2.5-10x42 the factory says the parallax adjustment makes it difficult to work with a PVS14, so recommended the 2.5-10x32 if you were going to use for that, they also said the newer 2.5-10 x 42's will not have NV settings for anyone interested in that sort of stuff.
