These complete hopup units are made from CNC machined aluminum and molded nylon. These offer superior rigidity and support to the precise hopup components. The adjustments on these have good holding force so they won't move from vibration or BB pressure. These advanced versions use a spiral wheel and lever arm instead of a series of gears and cam to adjust the hopup pressure. This system is generally easier to adjust and holds position better.
