This is the patented Spyder Gen3 Balance valve that has thrust Kingman forward into a new realm of low pressure stacked tube blowback performance. The technology is currently unmatched by any of the competition. It may be used as a replacement valve for your RS/VS marker, or for diabolical experimentation of your very own LP Spyderstein project marker. When matched with the light weight Gen3 shorty striker(not included), this valve has taken the running pressure of the RS/VS markers down to alltime low of between 200psi-300psi at a relative 280fps velocity with no recocking concerns.
