JT 90g CO2 Cartidges (88g Crosman AirSource cylinders Compatible) Description Crosman Corporation has discontinued their 88g Airsource line. JT comes to the rescue with these 90g tanks that are 100% compatible (although they are about .5" longer). Works wherever Crosman, Gamo or Walther cartridges were previously needed. Features: Compatible with any air rifle or paintball gun that accepts 88g cartridges. Approx .5" longer than Crosman 88g AirSource cylinders. Seller has personally tested in Hammerli 850, Gamo Extreme and QB79 with excellent results. Remember to always apply a drop of airgun oil to tip of cylinder and on threads.
