NF is the gold standard in optics I own several. They are tanks and worth every penny. Hard to compare NF to a $400 Tract. My gripe with the Response test was that one scope had NF rings and the Response had a Warne mount. I agree it shouldn't have failed but I never saw the mount or optic in question. I myself have never been a fan of Warne products. I've seen my share of issues with them. I'm a huge fan of AADMOUNT. I have that on my JP Rifles AR15. I feel the scope should have been sent back to the factory and been diagnosed. Maybe a bad unit got out there.
