The NEW HDS double-barreled Marker .68Cal from T4E combines power and speed. Thanks to its Co2 quick-piercing system it’s ready to use at any time. With a light blow on the bottom of the grip you can puncture the CO2 capsule whenever the occasion demands. The HDS comes with a Picatinny rail under the barrel. The large .68 caliber allows you to use rubber balls, chalk balls and paintball, which can be shot individually or simultaneously from both barrels.
