Other features that the Hop-up unit integrates in its design include an externally accessible dial adjustment wheel for easy, tool-less adjustment and hop-up stability against the vibrations of the gearbox, and a dual point-of-contact nub for exact orientation and even pressure of the hop-up applied to the BB, ensuring straight and stable backspin.
The RWA PTW Adjustable Hop-Up is the highest grade of PTW hop-up available, precision engineered and manufactured for precision performance and accuracy when combined with a synergetic PTW set-up. The Hop up unit functions best with the original Systema PTW Receiver and magazine. If you were to make a few external modifications, such as, using a after-market receiver and/or magazine, then the unit itself will not function to the best of its capabilities. You have been warned!
Does not fit the Hop Up Bucking from other brands!
