Ordered a 556 elevation knob for my Mark4 LRT 3.5x10 m2. Leupold's instruction for m2 knobs say to install the knob with a bearing to the right of the mark on the back of the scope. The scope was zeroed with the stock 7.62 knob originally. Know if I place the knobs on and line it up on the zero mark, which places the bearing just to the right of the "0" mark, it only allows elevation adjustments in one direction. I just didn't expect this. I believe the bearing is there to keep the knob from rotating beyond one turn. Could someone tell my what I'm missing hear.

Thanks

I would like to know this too.
