Key Features of the Ninja MagnaCap
  • Magnetically attaches to the mail foster fitting on your airgun or Ninja tank
  • Quick and easy to snap off and on
  • When removed you can stick the back of the cap to any metal surface

Please scroll down to learn more about the Ninja MagnaCap including additional photos and a product video or two if we have them.


The MagnaCap magnetically attaches to most male foster fittings like the ones found on the Ninja tanks. They’ll also attach to most male foster fittings on airguns saving you from unscrewing the protector each time you want to fill the gun.
