Finishing up a 338LM build and need to get a 56mm NXS on top (tube gun, 20MOA rail). Looking for a good set of tactical rings. The NF LW rings seem a bit expensive unless there is some value there that I am too dull to catch on to (very possible). The few ounces of weight don't matter to me, this build is a tank and the scope isn't exactly dainty. I'm happy to pay for value, but unhappy to pay for the sake of paying . . . What are your experiences, what do you like and why. Bad experiences also welcome! Thanks in advance!
