Don't pass on the Redfields without checking them out
I talked a friend into buying one of the new Redfield 2x7 scopes for his Marlin XL7 he was putting together. He ended up being very happy with it. I would compare the Nikon and the Redfield and pick the one you like best. Their pricepoints will be close together. Redfields are made in Leopold's Oregon factory. They have a lifetime warrantee not that you will need it.
Does your SPS have a 22 inch or a 24 inch barrel? I think that they are putting 24 inch ones on the SPS, just curious... I saw a guy with a new SPS stainless in 308 last fall at the hunter sight-in. It was a great shooter.
