Somewhere I read, the flat nub is basically the same exact thing as a regular hop up system, but instead, the bucking hop up bump and alignment bump are taken off via knife, sandpaper, etc. and then rotated. The bucking is anchored, and lastly the nub is basically this large, flat surface that pushes the bucking and giving it a "flat" surface of contact.
Is that right? Seems extremely easy to do and possible to get it perfectly on the first attempt. It also seems better for lighter bb, since applying a lot of hop up this way would be a lot harsher than R-hop.
