The RG-59 uses powerful 9 mm (.380 cal.) center fire blanks to launch pryotechnic scare cartridges. This launcher is intended to be used with the optional four shot adapter. The adapter screws into the barrel and allows simultaneous launching of any combination of up to four scare cartridges. This produces a bombardment-like effect resulting in extreme aggressive hazing. This rapid firing model features a swing out cylinder with blank ejector. Launcher holds five 9mm blanks. Comes with a muzzle cup, small cleaning brush and instructions.
