Paintball gun lot used 4 tippmans and 1 gryphon fx 98 custom cronus paintball

Tippman 98 custom with custom barrel. Tippman Stryker xr1 full electronic marker. All markers work but are used not brand new. I have tested each and they all fire. The tippman Stryker is full auto or semi auto and it senses a ball in the chamber.
