So this is not a blasting of your product because I really like this optic I think this is related to the SCAR. At first I was unsure about it but it has grown on me and this is more an observation of what happened along with customer feedback.
So I was shooting my SCAR 17 this weekend and periodically after a shot the illumination would turn off(using the illumination because the center of the targets were black). I could turn the illumination dial one click either off or to another setting and it would come right back on. The only way I could keep it from happening as frequently was to apply a considerably high amount of torque to the battery cover with the screw driver on my SAK. I was unable to reduplicate this with the optic on any of my AR15/5.56 rifles. I was curious if you have had any reports of this and if there is a fix or revised battery cap.
My setup is a SCAR 17, the SLx 5x prism in an ADM ACOG mount it also did it in the mount it came with. I tightened the ADM mount right on the edge of being probably to tight that had no change.
