This version of the JM Models is the JM DB 11 which is the only model in the world with a double barrel technique. It is delivered with 2 x 11mm rifled barrels (for 1.5 and 3.0ml dart syringes) and 25 bars manometer. It is easy to interchange barrels. This is an advantage to the user who needs to frequently change between the two barrels and thereby avoid having to ‘true’ the rifle precisely hit the target. This model can also be delivered with 2 different size barrels (for 5.0 and 10ml dart syringes), please see model JM BD 13.
