HopUp stability snob

An interesting concept which has amazing results! Instead of the standard tube-style packing, this 'H' shaped packing replacement forces the hop rubber into a more natural cup around the BB. So instead of the hop rubber just gripping the top edge of the BB, the 'H' packing will grip a much larger surface area and therefore offer more spin and finer adjustment.  Materiall  Polyacetal  Usage  For all HopUp devices  Purpose  More spin and finer adjustment  Package  1 pc
