A different version of the JM Model is the JM.DB Model, which is the only model in the world with a double barrel technique. The standard model JM.DB is delivered with 11mm and 13mm barrels. It is easy to interchange the 11mm barrel (for 1.5 and 3.0ml darts) and the 13mm barrel (for 5.0 and 10.0ml darts). This is an advantage to the user who needs to frequently change between the two barrels, and thereby avoid having to ‘true’ the rifle to precisely hit the target. The double barrel is also advantageous in the situation where one cannot choose the dosing level until arriving at the location and seeing the specific situation. If desired, this model can also be delivered with two barrels of the same size. Please see model JM DB 11.
