DANiNJECT has produced an easily convertible version of the JM Standard injection rifle to allow for rapidly changing individual requirements. With a total overall lenth of only 65 cm, JM special provides outstanding accuracy when darting from helicopters or vehicles over ranges of 15-20 metres. In addition, the short overall length is an advantage when maneuvering within confines areas. By installing the quickly detachable 11 mm rifled extension barrel accuracy for longer range darting is quickly restored, making this a truly multipurpose injection rifle. Other features are the same as for the DANiNJECT JM Standard rifle.
