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 have a built in adjustable STS system which used to prevent gearbox cracking, which is a particular issue in version 2 gearboxes.
