Who knows. I have seen zero shifts based on sun angle, ammo and probably just my mood. 1.5 inches isn’t much, but I am reporting anything we see — good, bad or indifferent.

I have gotten out of the habit of painting small witness marks on the adjustments, because the DP Pro optics have always held zero without fail for us. Will be putting them on the SRO to watch for movement.

Just got a call from my friend. He mounted a second SRO on a 320 X5 today, zeroed it, and made witness marks. After 200 rounds, the elevation adjustment had moved one click in elevation on the second SRO. He noted that the adjustment clicks felt less positive than on the DP Pro. He was going to shoot more today and observe. Given this is two units out of two doing the same thing, I would say SRO owners should watch this closely.

Moved one more click, in his shooting subsequent to my last post.
