I have two Rem 700's that I bought in the past 5 months. One I believe is the old style and the other the new. I adjusted both. Both looked very similar. In the older, the screws were larger and easier to adjust. In the newer the screws were much smaller, none of my allen wrenches seemed to fit properly. In both metric and standard wrenches, the screws appeared between sizes. In any case, I was able to get both adjusted to a nice 3lbs.
