I can\'t believe this After chasing around loads that seem very promising,only to have them suddenly fall apart,for weeks now. I have noticed my nightforce slipping forward, ever so slightly,every few shots.ARGHHHH!!!! Burris signature zee rings with the plastic inserts. Does anybody know how to stop this for sure ,and how much torque to put on the ring screws? I noticed they are spitting oil,I'll clean them first.
