The powerful .68 caliber T4E Tactical Blaster HDB 68 guarantees secure and easy handling. Designed for simple operation and immediate readiness for use, the TB 68 features a high-capacity internal tube magazine and the proven Quick-Piercing System. With a light blow at the bottom of the grip you can pierce the CO₂ cartridge right when you need to fire. Long-term storage and quick availability no longer rule each other out. The double-action trigger permits rapid firing of the sixteen .68 caliber pellets. Picatinny rails let you mount aiming aids and other accessories. For precise firing the sight radius extends over the entire length of the 330 mm barrel. Suitable for the wide range of Umarex T4E roundballs. For the use as a paintball marker, we recommend to use our Markingballs (MAB) or Chalkballs (CKB). When using classical gelatine-based paintballs, according to the construction, there is a higher likeliness of bursting rounds when feeding, or in the barrel.
