Just order a 556 elevation knob for a mark4 ltr 3.5x10 m2. The stock 7.62 knob obviously will rotate more than once. The 556 knob has a bearing to keep the knob from rotating beyond one rotation. The question I have is when I place the new 556 knob in place and line it on "0", the knob will only adjust in one direction. So if I want to make adjustments in the other direction... well I'm just not getting it. I just wasn't expecting to not have the ability to make adjustments either way after putting the knob on to line up at zero. The instructions say to keep the ball bearing to the right of the marker on the back of the scope. Basically it would always be to the right due to rotation. Could someone help explain what I'm missing here.
Thanks
