I love quoting myself...That was also my first thought. I never put an optic on my rail, in fact, I removed the rail on mine, completely. The way the mount is, right on the barrel, right in front of the chamber... that is probably the worst place to put a mount.
Now that I think about it... with your optic mounted on the Socom16 rail... which is mounted on the barrel right in front of the chamber... and you are having issues with wandering zero or shotgun patterns after a few shots. That optic mount turns into a heat sink and what does hot metal do? It expands... or at least tries to.
I'll also say that when I shimmed my gas lock correctly my POI shifted 5", but my groups tightened by 50%.
