Pulled my NX8 1-8 that sits on top of my Scar 17 out of the safe and the reticle was illuminated while on the off setting. It did not matter what setting I spun it to it always stayed on. If I go between brightness settings I can get it to shut off eventually but the next time I look at it, it is back on again. Newer battery, battery cap is closed tightly. Anybody have this problem?
