First, we weighed and measured the scopes to verify manufacturer specs. We evaluated resolution, color rendition, and brightness by looking at an eye chart and colored targets set out at 100 yards in dark timber. Then we mounted the scopes on a devilishly accurate Sisk STAR rifle with Talley tactical rings, and fired Barnes Precision Match ammo to test the adjustments’ precision and repeatability. Next, we tossed the scopes in the back of a Polaris Ranger and drove down a mile-long, kidney-jarring trail. After putting each model in a 105-degree hot tub for five minutes and then in a bucket of 55-degree well water for another five, we put them in the freezer for three hours. Finally, we checked zeroes and repeated the adjustment test. Meanwhile, all other features and functions got scrutinized. —R.M.
