You only need to turn them 90-degrees with the unlocked position being straight up or straight down and the locked position being straight forward or straight backward. Be careful about using too much force on the paddles as they are quite fragile and easier to snap off then you would expect. I like the design, but wish that the paddles were more robust. Leupold sells repair/replacement parts if you break them, but it would certainly suck if you broke them off when you were far afield. The fragile paddles have prompted me to swap out most of my Leupold QRs for Warne or Leupold QRW styles.
