These SHS buckings provide an easy accuracy upgrade over the conventional bucking design. The split nub changes the BB contact area from one to two points to better center the BB's axis of spin. While these buckings won't provide anywhere near the same effectiveness as an R-hop system they are a cheaper and easier to install solution. I believe the lip design is actually made specifically for A&K hopup units so may be incompatible TM style hopup units.
