Well I mounted it up on one of my rifles and settled into a proper cheekweld and it definitely toned the warbling effect down; however, I could still tell there was a fair amount of outer edge distortion throughout much of the mag range. Parallax was still pretty finicky (especially at close distances under 100 yds) but once dialed properly was spot on, no reticle movement in the center. Since we are typically shooting at targets with the crosshairs in the center this should affect center punching; however, for anyone who might use this to scan for targets like in a PRS style competition, I can see how the edge distortion might be a hindrance. Having had experience with March scopes previously I am not surprised at these issues as they are very similar to what I experienced with the March, but the NX8 is over a $1000 less when you consider illumination (by the way the illumination on the NX8 is fantastic and daylight bright to boot).
