Thanks guys. The rifle is a 300 win mag so not going to kick too bad.
I am leaning towards the Seekins now based on a few nit-picky details when comparing them with the NF.
Also, as a side note, I just bought a set of the new Vortex precision 30mm rings for a different rifle, and it appears that vortex has their rings made by seekins. They come in the same style cardboard box, sealed exactly the same in little plastic bags, they have the same exact "inspect by__________" stamp inside the box, and the design, anodize, machining, fasteners ... everything is exact compared to the seekins rings
. Could be a coincidence, but they are simply just too similar.
