The MK-4 is an ideal size for patrol officers to wear on a duty belt and will deliver 20-25 short bursts of OC at an effective range of 10-12 ft. This 1.3% MC OC aerosol product features a 360° gel delivery method which allows the aerosol projector to disperse OC from any angle while providing a target-specific, strong concentrated gel stream for greater standoff and reduced cross contamination.
