I’ve been using this scope for a couple of month on my Atomic XR and it has proven deadly and capable out to 51 yards on pests. And I plink with it regularly out to 64 yards. I have it mounted in a set of Warne Mountaintech rings, great thing is it retains zero when removed and remounted. Today I put the West Hunter on my Spikes Tactical AR15 .22 LR setup and with no adjustments. Was immediately busting clays at 105-110 yards using 1 mil of hold under, sending Remington HVHPs. Even took out two shotgun shells at 100 yards. Then I got home, put the West Hunter back on my Atomic XR, no change to my zero, first round hits from 25 to 40 yards in my backyard. The West Hunter and the Atomic XR are a sweet combo. I will be picking up another WHT for my AR setup.
