Hey survivors, I believe that I have discovered a glitch or maybe I am just ignorant of how to use it properly, but I have noticed there are no cross hairs when I use the ACOG scope. I have it mounted on a MP-5, I right click to bring the scope up to eyesight, and all I see is glass...no cross hairs. I have tried installing a battery...no option. I have tried "turning on", again no difference. Is it a glitch or am I missing something? Thanks for any feedback!
