I'm contacting holosun about a 507K X2 that failed after 4 shots today. I co-witnessed it on the F&N-502 rimfire pistol. Fired three shots right on target, then noticed the dot was stuck in the upper right of the optic. No amount of adjusting could make it move again, even when in a gun vise to eliminate human error.
Holosun has a great reputation and I'm not trashing the brand or model. Apparently, I got the anomaly that failed.
